I have attended a couple Search Engine Strategies Conferences in the past, so of course I expect one or two email notifications about the up and coming Toronto show. But I have to say, I must have received 10 emails about this Toronto show already. And I expect to get a few more before it the show takes place.
I think it might be because I am on several lists. One as a conference attendee, one as a newsletter member, one as a paid member of SearchEngineWatch and one as an advertiser at one of the events. This is not really an excuse to receive so many notifications about the same event. I am sure Danny Sullivan would agree with this and maybe send Jupiter a note on this, but I do not expect changes soon. It all depends on the number of people who complain.
