i am looking for a tagging plugin for Wordpress.

I know there is ultimate tag warrior. but i hear there are instability issues especially with WP version 2.1+.

there is also Jerome's Keywords, but again, there are instability issues. and then I found Simple Tagging which seems to be the solution for me, but I can't seem to get the tags to show up for each post. the instructions are bare minimal too.

any other suggestions for a tagging plugin?
