I like to stay on edge of new technologies, at least knowing that they exist. Therefore, as a user of Stack Overflow, I'd like to be able to see what tags are growing the fastest.
I know there's a small line on the tags page saying "X asked today, Y asked this week", but I'd have to go through a lot of pages to find the ones that have an interesting number compared to the total number of questions tagged with it.
So I was thinking about a page that would list tags according to their % growth over a length of time we can choose from (day/week/month/year maybe). Filtering out tags with less than X questions might help, otherwise we'd see crazy numbers for new tags.
Is this something that could be of interest? Or am I the only one interested? Is there any way to do it already?
