Yes I have many more likes on the FB page than people who have actually clicked like on the WordPress blog. Its the same for anyone following from Twitter.
If it wasn't for this connection, my likes would look pretty poor on the site. My blog has only been public for a month and only just starting to get visitors independently.
I currently have 61 likes, only 6 of these are from the blog itself, 4 are from twitter and the rest are from Facebook.
Hope this helps folks out, and if anyone comes across a permanent fix for this (without having to delete) please let me know :)
