bhartzer, I don't think because it's been removed from here you should move it from your site. Each case is different. If Brett's analysed the stats and removed it from here because it's useless in this context it doesn't mean you should. A post about php probably isn't "viral" to everybodys friends on Facebook and so doesn't provide real value. A blog post about some upcoming computer game may have much more appeal to a persons friends and so is more worthy of this viral exposure.
On Twitter however, I find myself more like to be following/ and followed by more people who might be interested in the php post.
So as I say, take everything on it's own merit. If the like button suddenly causes every site to slow down and spread viruses then by all means remove it. If it provides value to your site and your users then I'd say keep it.
