SnowMan - I think I've always been #1, or #2 for my main keyword, it's the semantic variation that has completely died off. No longtails is what is killing me. I used to be able to think of any related keyphrase and I'd be on page 1, now it's down to a handful of lower volume keyphase leftovers that G doesn't want or care too much about, or so it seems.
Str82U - you hit the nail on the head. I rank mostly for the EMD, and one synonym. Specific page titles and sub content is diluted out by well SEO tuned blogs and rehash. Site just got a minor facelift and now I'm starting work on retooling my blog for eye candy and responsive design.
