Clearwater marketing and tech firm Think Partnership officially switched Wednesday to a zippier name: Kowabunga! Yes, the exclamation point is included. The name might evoke memories of Teenage Mutant Ninja Turtles or Snoopy from the Peanuts comic strip. But a spokeswoman described it as "a wave of excitement that describes the enthusiasm we have for the company." Kowabunga! is a provider of performance-based marketing and technology tools for Web commerce. The former Think Partnership consolidated a handful of companies — one called Kowabunga! — in a Clearwater headquarters last year with about 100 employes.
