Most of what I need in my blog comes in the basic WordPress download. The only think I worried about was selecting a theme that suited my mood or my personality. I think I did well, with that pick.
But now I realize that there are some good extras you can download and install, called plugins. The best plugin is an anti-spam plugin called Akismet. It does an excellent job of monitoring your post comments for spam and it just deletes them for you. It works like a charm.
I’m about to try another plugin called All In One SEO. I’m not sure it will do any good for getting my blog better traffic and noticed by more people, but it can’t hurt.
