Some years ago I started rrrewind, a time machine of popular social content. It had good reviews when it launched.
At this point I don't have enough time to pour on it and I prefer to pass it to a fellow that loves the concept and who wants to take it further.
It was a personal project and no a for profit venture. It's up to you to decide how to go next. I just ask to be associated as the founder of it.
Stack: php. No DB, just a bunch of xml/json files.
Data: It contains 2 years of daily feeds from the most popular social sites and some unpublished.
Thanks
Thanks a lot for the comments & emails I'm getting. It's still time, I'll take a decision next week.
