Nsyght is a clever service with a terrible name (it’s hard to remember) and stock photo on its home page, but don’t be fooled – it’s really useful. I wrote about it on ReadWriteWeb last week under the title How to Search Inside Twitter Lists, and that’s just what it’s for. After a few minutes to index your stream, Nsyght will let you search inside tweets from your friends, inside particular lists or your own archive for months back in history. It’s awesome. I’ve been using it to filter for images shared by friends on Twitter (great for quick little posts) and to find old Tweets of mine that I can’t find nearly as quickly in any other way. And searching inside a Twitter list of topical experts for their opinions on a particular matter? So hot. It’s like a Custom Search Engine for twitter lists, which is incredibly powerful.

I think of things like this as curating my existing community resources, an all-too under utilized strategy I believe. That’s the kind of thing I’m likely to bring up as a guest tomorrow on Tummelvision.tv, which I cannot recommend highly enough that you check out.
