The largest English corpus I've found (over 10,000 messages) is the National University of Singapore's SMS corpus -- select the corpus with "all" messages -- however, closer examination reveals that relatively few of the messages originate from US participants.
A corpus of SMS spam messages has been created which are written in English. There are over 1,000 ...
What you're trying to do is called named entity recognition. There exist several typical datasets for it, such as:
CoNLL-2002: free. 4 types of entities are tagged: locations, persons, organizations, and miscellaneous entities that do not belong in any of the three previous categories.
CoNLL-2003: free. 4 types of entities are tagged: locations, persons, ...
You may be able to use the International Picture Naming Project (IPNP), but I think the total pictures are way less than 10k.
Here's a link to the query tool.
You may get lucky searching through "image recognition" research websites. Here's one compilation of online resources, and a particular one.
I've been thinking about this question a lot and I have another solution. You correctly wrote that Wikipedia articles have too much quality due to the editing.
But, the discussion (talk) pages are full of raw text data and are not prone to being edited, or even correct.
An example for the French language Open Data page (source):

Probably the Swedish Academian Wordlist (SAOL) is the most authoritative source in this field.
There exists SAOL for Android, the .obb expansion file is a regular SQLite database.
This list was extracted from the .obb database file. The list contains more than 90 000 nouns (whereas the list from dict.cc contains less than 9 000 nouns). About 75% of nouns ...

NL-SPARQL is a data set of natural language (NL) utterances to a conversational system in the movies domain and corresponding queries to Freebase in SPARQL. This dataset was collected via Crowdsourcing as described below.

I am not 100% sure if the following links are useful for you. Please let me know if you are looking for something else.
I don't know a corpus, but I know a way to create one. If you know how to program you can use the Facebook API and download all the public facebook status from USA with their comments. Then you can use them as a corpus.

I created a dataset with of on-line data. It has 369 symbols (including a-z A-Z 0-9 \alpha-\omega), but it is online data. You will have to create the rendered versions yourself:
Each class has at least 50 recordings. (I don't have much data for letters, so it will probably not be more.)
edit: I've redered it. See The HASYv2 ...

I actually ended up paying folks on MechanicalTurk to label questions as important/unimportant from a couple of news articles I downloaded. There are 410 sentences total, which I have on my github here.
Blurbs, or short descriptive material to promote a book, may be impossible to legally share do to individual copyrights of the authors or publishers.

How about movies?
Option 1: bulk download of French language movie subtitles. I haven't tried it, but OpenSubtitles.org has both instructions for programming and non-programming.
Option 2: Download plot synopses from the plaintext IMDB database (with reviews) - mirror links. Useful files are 'language.list', 'biographies.list', 'plot.list', etc. ...
I cannot help you with products review and you have already got an answer for Twitter. But if you need a dataset with plain text in french, the best solution is the Wikipedia Dump. I used it for another project in English for a similar reason (sentiment analysis and information extraction).
Here is the download link with all the info. The small dataset is 2....
I can answer for the Twitter data. You can gather plenty of French language tweets by one of two methods:
Live Stream. In this case, you can pass this URL: https://stream.twitter.com/1.1/statuses/sample.json?language=fr and you will receive tweets as the standard JSON dictionary. An example python code to download a portion of the public stream is here. In ...
Most telephone recording datasets are privately owned by parties who have access to such data like for example call-centers and tech-support companies etc. This data is subject to various privacy laws (which differ from one country to another), therefore it is tricky to find such data.
Nevertheless, the CallHome database and the CallFriend database -by ...
Project Gutenberg offers 57.000 free books, available in different formats. Among them, utf-8 encoded plain text with minimal formatting.
The NLTK comes with access to a range of corpora. Among them, a selection from Project Gutenberg, and a chat corpus (if you are looking for more colloquial use of English). Beware of the varying licenses that apply.
frWaC: a 1.6 billion word corpus constructed from the Web limiting the crawl to the .fr domain and using medium-frequency words from the Le Monde Diplomatique corpus and basic French vocabulary lists as seeds. The corpus was POS-tagged and lemmatized with the TreeTagger, more information available here.

You can collect email data in .mbox text files using a search engine. For example, a google search for filetype:mbox from results in plenty of .mbox data. My best attempt at French-only .mbox files is this search.
Individual .mbox files can be concatenated into one large file (linux method):
cat mboxfile1 > mboxfile
echo >> mboxfile
cat mboxfile2 &...
If the number of addresses is thousands at a time, and not more, you can use the Google Geocoding API for free. You can even use the API without a key for small sets of addresses.
The URL looks like this:

And returns a JSON with structured ...
microformats do that, off hand look @ web data commons for a large repo:
more real world examples from microformats wiki:
Based on @NeilSlater's comment, you can easily calculate character N-grams with a few lines of code.
In this snippet, I use Python's Collections library, which is quite fast for these types of applications:
from collections import defaultdict
data = defaultdict(int) # for speed
for i in xrange(len(text)-N+1):
You can find homework assignments that are submitted as forks for a MOOC Github repo. In this case, you'll find multiple SQL statements for the same question. The SQL style will be a little biased because all the students are following the same course.
