Never been to Ad-Tech. SES & PubCon have a fair amount of overlap in that the same industry reps tend to present at each. There are plenty of events after the sessions at both. SES skews more toward the marketing manager stereotype & WebmasterWorld skews more toward the affiliate, smaller business, and hands on crowd.
