Just a few quick things...
I deleted a two comments from this blogs this morning that looked like spam. I have one spammer that pops up once in a while that I know isn't real, but these were from someone who seemed like a legitimate poster, but then had a link below that looked like spam. When I checked the poster's profile, there was nothing there, another clue that this was spam.
Now, I don't mind commenters posting links to your blog or website or whatnot in your sigs, as networking is one aspect of being in an online community. I even try to link to the sites of my regular commenters as a thank you when I see them. But for those who post only to get a link in there for my readers to click on and sell something, it's gonna go bye bye. I'd prefer not to put my readers at risk of who knows what at the end of that link.
I guess I should be pleased that the blog has gotten big enough to start attracting spammers (grin).
EDIT NOTE: If I accidentally tag you as spam and delete you, just let me know and I won't do it anymore. Sometimes a real comment can look like spam.
In other news, go see Iron Man 2. It totally rocked. Better than the first one. I'm so going to go see it again soon.
