Thank you all for your comments. I've just been curious about this. Guess it's just the nature of the beast.
The spam for the most part, has been going to the spam folder, not much to the actual comments on my posts.
I have noticed alot of comments coming from friends with Google blogs are also going to the spam folder. This never happened before. That's actually when I started noticing the increase in spam. They told me they commented, but it wouldn't show up on the respective post.
I have to laugh about the type of spam -- most relate to SEO and increasing my visibility, with a little porn thrown in (the website titles are a giveaway).
As an aside, Timethief - great minds re: posting at the same time! Thanks for pointing out that my picture link is private. I didn't realize it still had my old website attached. I've changed that. Also, I absolutely love your blog, it has been immensely helpful to me in the past week or so. Would love to know how you do a few things that you have in your sidebar.
