I've literally spent most of the last week trying different WP social plug-ins - there must be at least 50 of them! But every one of them had a problem: it was either slow, buggy, ugly, lacking a critical feature, lacking a critical service, abandoned etc. But not this one - this one has it all! Yes, it is a little more work to configure due to its extraordinary flexibility, but IMHO it's well worth it! Don't waste your time like I did - just get this one.
