AdTech is now the biggest show in the online marketing community, bigger than Search Engine Strategies.  Mike Grehan said there were over 10,000 people in attendance.  

There’s also another Bill Hunt - Mike Grehan picture below - I think they’re now taking a photo together at every conference (which is most of the big one’s); they are both established players in the Search Engine and Internet Marketing field.

BTW, I saw that stick at the hotel bar in Boston when I went to Webmasterworld. 

In a recent post I covered a story that showed there is not one Blogosphere; there are now at least 4 Blogospheres.  Why is that?   Simply, interests are diversifying and new communities are forming. 

I see the same thing happening with AD-Tech, Search Engine Strategies and Webmasterworld because the field needs some new people and new ideas.
