I have a Google follow me that I added to my Wordpress.com site (it can be added there). I think it's easier for people to use & there is a benefit of calling attention to those following in a positive way :D
Melissa great question! I have the same one too! I like to follow back but sometimes there is no link to there site. Maybe they are not following publicly? So you can not see their site? I have no clue! Let me know if you figure it out!!
