SEO bad days

OMG, what happened to SEO with respect to this tech blog ? Help...

Not long ago, it was at its peak... MSN=No.2 (Tech Blog), Yahoo=No.30(Tech Blog)..

Right now, as at now, it is nowhere to be found from MSN, Yahoo or Google for category "Tech Blog"

MSN usually only updates its cache every two weeks per se. I have to wait for two weeks to see if this blog had been totally terminated.

Such a dark day for SEO in my own terms.

Anyway, I'll be back, stronger.
