I've known QA Analysts who became very upset when called "testers". There's an idea that being an "Analyst" means you analyze the quality of an application, which involves more than just testing. Being called a "tester" implies that all you do is test and nothing else.
There are a lot of strong opinions about whether we are in the Quality Assurance or Testing business.
I really like Michael Bolton's blog post on the subject:
