I just wanted to say that I checked out your profile (very quickly), and my #1 suggestion would be to get a meaning picture into all of your hubs. Your Profile picture is fine for your profile, but it's a bit 1984 when it comes to looking at titles of your hubs. Heh! People are visual creatures (and I'm sure, I'm not alone on this one), and we want images that help us connect with others. I bet if you give that a try you'll get more readers and followers!
Hope that helps!
