Do you think it is spammy ? I think it adds value. What happened was It occured to me as a useful thing to post and then I considered which of my websites to put it on.

I think google does a pretty good job of providing good incentives. I mean there are a lot of people competing to create content that other people are interested in. That's a lot better than many of the alternatives.

My 2 cents.

I never complained its spammy! It is one of the useful ways of boosting your page rank and getting it linked.
