Lorelle has posted a great introduction to Ultimate Tag Warrior. She covers almost all the basics on what makes UTW my favorite plugin.
She has also been reporting on feed stats. Now whilst I don’t want to be accused at looking at her “details” again, if you add her WordPress.com subscribers to her Feedburner subscribers then her total is approximately 2500 subscribers. I am sure she also gains a lot more readers through various other interfaces on WordPress.com who don’t use a feed reader.
