Trevor Cook: Pubsub - what's going on?

Pubsub - what's going on?

What's going on at PubSub? There has been no explanation for these dramatic changes - were the previous ratings wrong or are these ones? Corporate Engagement dropped from 2200 to 36844. Is it really possible for the rankings to change that much that quickly? If so, why? and does it really mean that the rankings are really pretty random? It seems quite a few people are in the same boat.

Something seems to have changed with PubSub's LinkRanks the last 24 hours. My ranking has dropped considerably, and so have several other blogs that yesterday were in the top 10,000, while many others have seen no change at all. I know that the rankings can change substantially overnight, but this seems to be more than a coincidence.

Apologies for the triple trackback - the first two times it gave an error and I assumed it hadn't gone through.

James wrote on his blog - "Oddly, Trevor Cook and others are reporting their rank has dropped recently. Perhaps some highly weighted bloggers just dropped out of the time-weighted window of referrers for their sites."

Well my technorati links / sources numbers haven't changed on Technorati and two days ago I got a big spike in hits after Robert Scoble linked to one of my posts. No the odd man out here is PubSub as far as I can tell.

Hey Guys,
The reason for the sudden shift is that we increased the granularity of how we measure linkranks. Specifically, we added individual blogs from the various hosting services for the first time (e.g. livejournal.com/johndoe) - that has suddenly shifted everyone's ranking. Bob Wyman, our CTO, dropped 30,000 places (much to his chagrin). Check out his blog for more details - http://bobwyman.pubsub.com

Cheers,
Salim Ismail, CEO

More Women Blog Than Men Its certainly true that the political pundits are overwhelmingly male but across the blogosphere the numbers are much more even. And women are more likely to stick with it. So those fears that women would be left out of the new publishing revolution seem to be ill-founded. Link: Blog Brandz: More Women Blog Than Men.

For those who would have our kids with eyes of glass and hearts like tape recorders It's just 37.5 hours till Santa slips down our chimneys here in Sydney. As the "Dadda" of a 21-month-old boy I was moved by this piece on the magic of Santa by John Birmingham. Merry Christmas and a safe and prosperous 2005.
