For instance, when I mention #science in a comment or submission, could it link directly to the tag page for #science? I know mk is trying to avoid tags turning into subreddits, but I honestly don't think this feature would contribute to that. It would contribute to user discovery, though, since whenever a tag was mentioned in conversation, a simple click would lead users to the tag page, which would display a whole host of users who submit content with that tag, and hopefully they will find a few new people to follow as a result.
On a side note, I would also like to make the "ignore this tag" button more obvious on the tag page somehow, just recently I noticed a long-time hubski user had no idea you could ignore tags. I'm certain he isn't the only one.
