@decart- Yes #catwest was a great place to connect with Tweeters. I kept looking around and everyone was on their phone..not that everyone was tweeting…but I assume many of them were. Who was your favorite speaker and why…if you can pick just one?

Thanks for your words. Yay twevangelists! (term I heard from @danatwichell).

The thing with hash tags is they are not a "directory" but a tag. What's the difference? Think of a phone directory: It is compiled by a central source that decides what to list. Or a folder on your computer (aka "directory): You probably organize some documents by topic, by placing them in a folder. In that case, you are the central organizing source.

A tag is different from a directory in that it is not necessarily controlled by a central source. Consider: Person A defines a new tag "Foo." Person B posts something. Person C says, "That's cool, I'm going to mark that as a Foo." The organizing power is not centralized, but distributed; it's the "hive mind" at work. (Because of the nature of Twitter, person B and person C happen to be the same.)

Clear as mud? I suspect that you already use tags in other contexts, such as managing your photos. They might be called "keywords" instead of "tags."
