Where to upload open data? (no online data editing needed)

Question

I have CSV and RDF files that I would like to upload somewhere so that everyone can download them.

What is the most appropriate website for this?
I need at least:

1. Easily upload, just select the license, enter some info and upload the file. No need to wait for anyone's approval
2. Ability to replace the file with a new version, URL does not change. (just upload file to overwrite. Online line-per-line editing features NOT needed)
3. Accepts most text-based structured formats: CSV, RDF, XML, TXT
4. List of the files, and download button for each
5. Direct HTTP link so that the data can be downloaded by a script
6. Anyone can download without any registration
7. File download statistics are visible by everybody

Bonus for format-aware features:

• Preview of the data (eg. First 3 lines if CSV, First 3 triples if RDF)
• Data browser
• For RDF, generate hyperlinks to other linked data
• Re-uploading the file does not reset the statistics

Tried but failed:

• Dropbox does not show download statistics
• Sourceforge is for source code, and I am not sure how far they tolerate big amounts of pure data

Answer 1

Well my comment received a number of up votes which I take as a signal of quality and I am posting the links here so they are more visible to future visitors:

• opendata.socrata.com - you can upload a number of different file types here, create visualizations, link to them, and take advantage of a very mature set of APIs for data consumption and publishing
• datahub.io - like opendata.socrata.com, datahub.io is an open data portal but it runs CKAN which is free and open source unlike Socrata. CKAN is modular and you can write plugins for it but in my experience, out of the box, Socrata has better visualization and mapping tools
• github.com - You mention SourceForge and I would recommend taking a look at github instead. You will have limited analytics compared to the first two sites which are built specifically for what you are looking for but Github has a lot of advantages like the ability for folks to fork your code and they do render CSV and GeoJSON documents nicely now. Also take a look at this blog post by OKFN (folks behind CKAN) for some suggestions on how to use Git (and Github) for Data
• quandl.com and modeanalytics.com - these sites seem promising but I have not had a chance to work with them as much and they do not appear to be as feature complete or widely adopted

Knoema is the free to use public and open data platform for users with interests in statistics and data analysis, visual storytelling and making infographics and data-driven presentations
