Really? I am a perl expert, yes an epxert. I have been programming in perl more than 8 years and produced few serious programs, one is far more complex than MT. I have gone through MT and many other programs, your arrogance shows that you don't know how to evaluate MT. This is a problem with technically challenged people, since they don't know what they are talking about. But, for you I have a tip. Try to check out the features if you can't understand the perl code to really understand where MT stand. You should also check out other programs, trying to evalute MT by itself is meaningless as you are trying to do. You got to understand what MT gives to judge what you should pay for. Right now MT's bigggest advantage over WordPress has been multiple blogs, but even that's not a big issue. You can still use WordPress for multiple blogs. Now that most of the users of MT is moving to other platforms, watch out how SixApart fail miserably. You can't ask 1000$ for something that worths 100$, similarly you can't ask for 600$ for something that worths 50$. People will not pay for these set of features no matter how many lies you spread.
