Not my latest work (2 months ago) but just post it out anyway. Well, I am not developing my own plugin to do that either.
It is so convience once I setup up the Auto Publish to facebook, every word and picture will pick up from your post in wordpress and publish to facebook. So, no need to update both their wordpress site and facebook (even twitter if they have one) anymore.
Well, there are kind of lots of setup and you need to setup your company facebook page, facebook development account, and sure you must have to host your own wordpress, then install your plug in and put all the setting in. Take me 2 to 3 days to figure out, but I am sure it is easier for average user.
