Yes and no ;-)
Yes, as far as the SEOs are concerned: I will be presenting 
GoodRelations + RDFa at SES 2009 in Chicago, likely one of the most 
important SEO events, and there is already give some interest among SEO 
experts in GoodRelations.

SEOs will have a huge market opportunity for helping companies optimize 
their GoodRelations markup. It will turn SEO from the art of improving a 
rank to the science of minimizing the search effort for a very specific 
target audience.

No, as far as Yahoo and Google are concerned: Their current moves are 
into the right direction, but in my opinion much too slow and cautious.
Additional details in Google and Yahoo search results are nice for 
convincing a local business to create a bit of GoodRelations markup. But 
that would be exploiting only 1% of the business potential.

Getting the remaining 99% of the cake will require different technology 
approaches and business models.  I guess they will smell the cheese and 
increase their investment fundamentally very soon.

So it may be good for a small business to see a bit of extra data in 
Google, Yahoo, and Bing. But the real target applications will be more 
fundamental innovations.

To my knowledge, both crawl only a predefined list of vocabs. 
Fortunately, Yahoo crawls standard vocabs, Google invented their own

You have to ask Yahoo :-)

For events, I don't know. There is an austrian initiative, but it is 
still pretty much alpha.

As for the price: GoodRelations. Because, again an important 
distinction: It is not the event that has a price - it is a ticket 
(permission) to attend the event that has a price ;-)

There will be a respective recipie at
