From my post on top wordpress Plugins
I use:
WP Notable: "Notable displays a series of icons below each post allowing your readers to easily submit you to many different social bookmarking and networking sites."
FlickrRSS: Flickr images on your homepage, a great tool for integrating your photos on your blog.
Related Posts: Related Posts is great for you and your readers, when it comes to reader retention, that is keeping people on your site, its a nice option to let people be able to read posts related to other articles you wrote. Related posts does just that.
Ultimate tag Warrior: This is the essential Tag Tool for wordpress, there is so much you can do with it, each post can be tagged.
Google Sitemaps: After all your hard work posting, its a good idea to make sure Google Search Engine knows about every page/post on your site. Google Sitemaps does just that, simple to install, once you have set it up head over to
Google Webmaster site, and you can inform Google of the location of the Sitemap file.
