At the Design show and workshops I attended this weekend, the speaker, Jerome Raska, was adamant concerning theknot.com. He highly endorsed getting into the site some how and checking it out thoroughly for tips and hints. I think he forgot that he was speaking to about 95% of the audience was from small town Maine...less than 20K population for most of the audience. For the larger cities here (maybe 7? of them over 50K pop.) there may have been attendees numbering in the single digits. I did the registration which is how I know the numbers.
I can see how theknot.com could make or break a florist especially in a highly populated area but I think I would try to stay OUT of their discussions if I were able to. IMHO
