I find that it looks kind of goofy, since I associate that character with a name of an IRC channel. That does suggest though the use of a # namespace where you could reasonably tag something with a tag like #a2b3 and then have a way to tune into everyone who used that tag recently (a la what you can do if you are a user and someone tags a post with @username).

Though really this is the only possible version of tagging on twitter which could work, statuses tagged with inherited context.

That said I think that features which need new syntax are going to appear very very slowly cf. groups.

Thinking a capital A at the beginning of the line should clear all sticky tags.

I like the idea but, for sticky tags, I can’t see anything more than a conference tag to be actually useful AND easy to manage.

Tagging IN the message might be useful but seems like a lot of overhead when we’re already limited to 140 characters and not something I could see people actually starting to use. I don’t ever wish I could filter out my friends posts. I never know what I’m interested in until I hear it — that’s the beauty of Twitter!

Take this post from Robert Scoble who does occasionally have something intelligent to say, but not in this case: “I’m done filling up Twitter and peeing in the pool for tonight. Good night!”

I don’t really need this zipping in to my cell phone when I am looking for that golden nugget of information. By tagging I could have filtered this out.

But, I can see a set of problems with the Twitter experience that might be helped with something that adds a bit more context – and something like tags seems like a lightweight and somewhat simple way to do it. Making them sticky helps make them less cumbersome to use.

I’d really like to be able to pick and choose the sorts of updates I receive from people I follow, across different means of receiving them. For example, I might not want to get all of someone’s random ponderings on my phone, but I’d like to get pinged when they start talking about when they’re leaving for the party tonight. If they switch to a new set of tags I’m watching for, this can happen.

Or, maybe after a Hack Day London, I’d like to go back and see what the chatter was about – ie. I can see what went on via the hackdaylondon tag on Flickr, and I’d like something like that for Twitter.
