Embedding a 'Like' box would mean that Facebook gets to know about who (IP address), when, where from and which pages any of our website visitors viewed. I don't think they need to know that nor that they should know this. To not let down those who - for reasons I do not understand - think that Facebook is a good thing, we could put a small Facebook button styled image on megaglest.org and have it link to the Facebook page on MegaGlest. We could possibly do the same for Twitter, replaying the contents of our 'news' page there if it can be automated.
When we link to such services I think we should also point out that we actually think they are bad, or which parts of them are bad. If we decide to do this, too, then such a note should be visible but not get in the users' way.
