I'd like to build an RSS feed for my website's twitter. It would be a feed of links that interest my user demographic-- college students.. the links would be funny, informative, interesting, etc. Just something that'd make my demographic want to follow. I'd want to avoid anything NSFW, so I probably want to avoid far-out humor sites like collegehumor unless they're linked from a work-safe blog.
I already understand the technical side of building a feed, I was just wondering how I can compile a list of sources for the feed.. if it was based on some kind of solid marketing research (e.g. college students are known to follow so-and-so top 10 sites more than any others) that'd be great.
I'd really like to avoid paying for any marketing-research services as we're on a tight budget.. SO free would be the way to go!
