Posterous is Not in beta

Fuck no. Under conventional ("software engineering") definition, beta is a stage when a product may be missing few features (e.g. complete help system), but when you can already show it to the public. Unstable versions or those missing major features are labeled as alphas if they are released outside of the development or QA. These are typically released in a restricted fashion and are not available to a general public.
Maybe they're in gamma? Maybe, like Hadoop, they're version 0.X? I'm sure rantfoil can enlighten us.
I don't use it myself, but I can see why some others might.
It's just another meaningless buzzword at the end of the day.
I don't think Posterous is in Beta or Gamma or Epsilon or any other nonsense. It's just... Posterous!
It's not all about being able to blame bugs, it's also a good marketing strategy to make users feel privileged or important.
Beta doesn't mean your code is bad, it just means you're not at "version 1.0". There is nothing wrong with launching your app in beta for a few months.
Not to mention that if you impress your beta testers, you'll have them acting like your marketing force at launch.
In the end, a well-run beta can do wonders to the quality of the launched software. So please don't go poo-pooing beta testing. Yes it's an abused term but it's still a good thing for those that know how to do it.
