I just found out about the tag/category limit (no more than a total of 12 for inclusion in "global tags"). Sure sorry to hear about this. I just wanted to plead for an increase in that number, like maybe up to 20 or 25. It seems unnecessarily confining to me.
For example, see http://writingreadingandreflections.wordpress.com/2008/06/29/famous-women-youve-never-heard-of-2/ for a good number of tags, but most, if not all, I think, are entirely justified. I guess I'll need to go back and delete some, but even at that, I'm sure I'd still exceed the limit. There's a few things I can drop, but because of the variety of topics, well, I need a lot of tags. Especially when multiple tags are needed for similar or synonymous terms such as "African-American history" and "Black history" for example. Or for a unique name that is an ongoing series on my blog, (like "Famous Women You've Never Heard Of") and so on.
Just wanted petition for this. Thanks.
