I always felt that the hashtags were a good idea, but that everybody was using them wrong. If, for example, my tweet looks like this: "I had a great time posting on Hacker News #hackernews, #great_time" then I am doing it all wrong. I thought the smarter implementation would be to do something more like: "I had a #great_time posting on #hackernews" It doesn't eat up as much space, but the inclusion of the hash allows for content grouping and all the other nonsense it provides. The first time I saw it used in the first way, I was kind of sad for the author, as I believe that the intent was for them to replace words, and the author just didn't get it... but I've seen it misused more than I haven't, so either the world at large is doing it wrong, or I am misunderstanding something.
