Turn your Twitter stream into your friends' linkblog JUL 23 2012
A few weeks ago, Twitter added an option to search the tweets of only the people you follow. This is useful for several different reasons (try searching for [recent pop culture key phrase] to see what I mean) but for those who use Twitter primarily to find cool links to read/watch, it's an unexpected gift. To view your Twitter stream filtered to include only tweets containing links, just do a search for "http". Simple but powerful.
ps. Who knows if they're interested in this or not, but by a) making their entire archive available to search and b) allowing people to limit their search to their friends + 1-2 degrees of separation, Twitter could significantly better the search experience offered by Google et al in maybe 25-30% of all search cases. This is what Google is attempting to do with Google+ but Twitter could beat them to the punch.
Update: The search above, while quick, is also dirty in that it will include non-link tweets like "My favorite protocol is HTTP". The official Twitter way to is to use "filter:links", which will avoid that problem.
