I think that the title tag is an important ranking factor, and if it is over optimized, it can have an effect on rankings. I think that it would be good to improve it.
I agree with you that my post is long, but I just wanted to provide some information to determine which one would be the better one to change it to.
I also mentioned the exact match internal link because I have read that this is being looked at by Penguin. I did not use an exact match phrase for SEO reasons; I used it because I think that it tells the visitor what is on the linked to page, but if this is seen as over optimization, I would like to change it.
