Does google index blog comments?

I was chatting to Dave Duarte about this today and I started wondering about whether google indexes the comments posted on my blog. The reason I ask is that if someone is taking the time to reply to something of mine, I think that it’s fair that they should get a bit of love for that in the way of a link. Yes, I realise that the potential for spammers to take advantage of this fact exists, but hey – that’s why we moderate comments right? My question is specifically for wordpress.com and wordpress.org posts but if you know the answer for blogger, well then don’t let me stop you…

I realise that Ias with most questions on the net) this was probably dealt with before, but if anyone knows the answer to this, or can point me in the direction of a site where I can find some guidance, please let me know in the comment section, which may or may not be indexed by google.

Cheers,

Lester

P.S – before you think I’m a lazy bugger, I did try and google it first, but didn’t find anything that answered the question.
