like twitter?

that could be an option, but there are already tons of twitter clones, i'm thinking something like Path

or maybe ddg could go into a partnership with diaspora

This is sort of in progress, for the long term, actually; as part of the Community Platform

For the record, I've been using Path and like it. Check out the size of their team :)  https://path.com/team

you could host your own diaspora pod, and integrate it with http://dukgo.com/

I started a photo based social network, and must say it's harder than a search engine because you have actual users. You're welcome to join my social network FreezeCrowd if you're in college or have a school email.  DuckDuckGo has been very helpful with doing the research for the site.
