PERFECT place to promote your blog. That's how the Internet works. I know y'all blog police don't get that, but that's part of the whole thing. Your statement proves you have no clue. Unwanted blog promotion would be if he was spamming links in comments, not posting his content. Pull your head outta the past.
No your statement means you have no clue. Often times, they just post their little blurb and never even engage in conversation. He can take his blog and shove it. this site is not here to enrich him. If he wants his voice heard then post his entire screed. If not, then leave.
