Just wondering if you guys still think its effective? I've seen huge jumps in my serps (from page 4-8) to pages 1,2 for all my keywords. I don't want to jeopardize what I built for a few links. My site is 2 and a half months old. I initially used blog commenting to build links (sporadically, certainly not the basis of my marketing plan). Some of my most powerful links has come from a blog comment (according to ahref). I have not been blog commenting since all these Google updates. As you can see, i'm a bit hesitant to resume that. Do you think I am being overly cautious? I always take the time to write a good, meaningful responses to whatever blog i'm commenting on. Thanks, look forward to hearing everyones thoughts.
