The one aspect of Facebook Groups that your article overlooks is the benefit of joining them. Back in 2008, when I was still using my old profile, I joined groups that interested me and interacted with other members. I think doing so helped grow my friends list as well as likes, comments, etc. So, from a business standpoint, joining groups that are in some way related to your business could be useful in gaining more exposure. I plan on trying this myself. The only catch is you can’t join groups using a fanpage. You have use your profile to join.
Also, in an earlier comment you mentioned that Facebook can be fussy about using a profile for business purposes. Do know any specifics? How are they fussy about it?
