Caspian SEO Blog is now a Do-Follow Blog.
This means any comments you make are dofollow and you’ll benefit by receiving link juice from your comments
However to stop spammers, you must register, you wont get dofollow until you have posted at least 2 valuable comments (e.g. i agree, yes, and other crappy little comments will just get deleted and wont count!)
I have taken this step to reward my regular visitors 
that is really a great news…It is always good to read your blog and now it will be beneficial from seo point of view too…that is simply great…
I found your blog on Google and read a few of your other posts. I just added you to my Google News Reader. Keep up the good work. Look forward to reading more from you in the future.
thanks for posting this your information might be very useful for the SEO peoples
