You'll never do SEO, but that is such a link bait title.
Secondly, I have nothing against SEO, just what it has come to be in recent times. I think it makes perfectly good sense to say, post your own camera review in the comments of a post on the same camera. Doing this on several websites/blogs will better your ranking while also helping people who're looking for camera reviews.
I just hate people spamming useless content with links attached for the purpose of SEO. I hate it even more that people buying websites have come to expect the sort of gains that you would get from such activities.
