I'm quite excited. I put an information / tutorial site up on the net (January 05) about a technique /skill where there previously were no free information sites. I searched for the informationm for a friend and couldn't find it - so I put it up on the net.
I did no promotion other than mention it on two related sites of mine.
Immediately I started getting loads of e-mails of the "really useful stuff" variety. Loads of people linked from related forums. I got some great positions in Yahoo and MSN almost immediately.
Then a blog on the subject put a post up to the effect "people keep asking me this stuff - find it here" (on my site). But for some reason they sitewide linked my new site.
Today the main site is grey bar (although the forum subdirectory is still PR4).
Maybe it's a glitch, and I can't understand why a sub-directory would still have PR. But I'm thinking a possible penalty.
It's funny - this is the only site of mine I can truely say is white hat. Normally they go a little grey hat after a while.
So what do you think - have I been Google Bowled by natural linking?
