Update: I don’t recommend this plugin anymore due to the poor customer service outlined here.
Here are three alternatives for your WordPress social sharing plugin needs that are free and work well.

This week’s WP Plugin spotlight belongs to Sociable. It’s an amazing way to allow your visitors to publicize or bookmark page(s) on your site using Facebook, Twitter, Delicious, etc. The installation is no brainer from the WP self hosted admin panel, just go to Plugins and Search for “Sociable” and select the “Sociable for WP 3.0”. Note there are several choices, but this is the one that works best for me.
Once it’s activated, all your pages and posts will have a bunch of little social network app icons at the bottom (like this post) where visitors can recommend or bookmark your pages easily. Sociable is another “must have” WordPress plugin in my book.
