I have been trying to
get what Twitter is about and trying to make effective use it. Currently I use it (via TweetDeck) to be aware of happenings in areas of web analytics, conversion optimization and split testing and indeed find it very helpful to keep on top on industry happenings. I also instantly reply to people, which helps me connect.
Just wondering how HNers make use of Twitter, if at all? Any specific use cases that you find helpful?
