The answer is... these are all new bots on the site this week!
From user agent hacking to shout-out advertising via user agent, here's the scoop:
Wink.com sent it's bot WinkBot/0.06
to index our content, and likely send us some traffic from it's search engine
Marcus Walker gave himself a shoutout in our user agent logs by proclaming to be
#1 in Business Networking.
Yes, it's pretty pathetic, but it's creative at least. Who knows - maybe Marcus is a pioneer in User Agent advertising, and he'll get the last laugh once he's made a billion dollars.
Not much to say about page_prefetcher.
Google doesn't even have a result when I search on this, so maybe we'll be the first in a few days.
Now 10 days into February, we have 58,088
user agents and 790 bots
