I saw this great post from Mark Suster of GRP today, and found it on Twitter of course. It’s worth reading, and he frames it around information discovery and starts with a primer on the history of RSS, Feed Readers, and del.icio.us. Personally, I’ve stopped reading my RSS reader, and get pretty much everything I need for work/business from Techmeme, email newsletter/blog subscriptions, the WSJ on the iPad, but mostly from Twitter – from the 641 people I follow but more specifically from the few dozen where I get their updates sent to me directly over SMS.
Twitter has been extremely useful for due diligence (seeing people tweet about a company I never heard of before, and comparing the buzz on one company versus another). I can remember a couple years when Tim Russert and George Carlin had died about a week apart from each other, that I learned about it first for both on Twitter. There’s lots of noise, but if you know how to listen and work it properly, pretty much everything you need will find its way to you on Twitter. If you still think Twitter is just for poeple updating what they had for lunch.
