White Hat way to do blog commenting

[ilyaelbert]

Do you guys think careful blog commenting is still a valuable day-to-day linkbuilding tactic? If I create a list of relevant unspammed blogs, and spend maybe 30 minutes per day commenting on 3-5 of them per day, while making sure that they're not inundated with spammy comments - is that worth my time?

I think if you comment on real blogs and write real helpful comments it is worth it from a seo and marketing point of view.

I think that your time would be better spent working on your own site - especially after you have already gotten one or two posts on these "unspammed" blogs.
