Not sure if it's what you're suggesting specifically, but if you analyzed common links within a span of time and analyzed them for keywords, you could associate other tweets from certain individuals. Tim Bray or Zed Shaw, as random examples, could tweet about an issue without providing a link to it (to infer context), but you could infer context by looking for relevant links from similar people.
If the system analyzed the links you clicked on (via the t.co URL shortener Twitter operates), the links you posted, and the topics you tweeted about, they could build a profile of interest for you and highlight those tweets.
Their current 'you should check this out' system on twitter.com and in the twitter client seems to be 'hey, here's some stuff everyone else likes', which (the last time I looked at it) was complete tripe about idiotic topics that 'the masses' care about, with nothing about the sort of tech news or political/economic interest that I tend to prefer, but I feel like a personalized feed is something that would be far more useful to me, and probably many other people.
