More than 350, but it's not important how many FB friends I have, the most important is how I can make business networking with them. Fortunately some of them are admin/creator of business private groups, so I can join the groups and get some projects
you know there is a max of about 5000... if you want to build a list for business purposes, you might want to look at fanpages, these are unlimited
I manage several fanpages and you need to spend a lot of time and effort to cultivate a following and interest, especially if the product/service is not very compelling or unique.
I just started my Facebook account last week cos i used to be unto my Myspace account. I now have 75 friends ad still growing. cos every time i opened my Facebook account I could see alot of invites from different people..
i never count my frnds, bcoz more frnds help u to get more visit. u need to provide link details also to share with your frnd.
