All the wild conspiracy theories are the correct answer.

I'm sure it has nothing to do with the fact that you are limited in cashing out deposits, or that investing/spending bitcoins has literally a 50/50 chance of someone taking your coins and running.

Nearly every bitcoin business venture has turned out to be a total out-and-out scam and you have had two ponzi schemes that were brazenly labeled as such.

Exchanges shut down regularly and often without any warning or explanation.  They are also hacked multiple times.

Mybitcoin shut down and offered you guys 49% of your coins back and you treated it as a victory.

Your list of bitcoin accepting vendors is 90% broken links and 10% stuff that could be bought cheaper with USD.

Anything you can buy with bitcoins still ends up converted into fiat money.  Bitcoin serves as a pointless middleman, not a currency in and of itself.

Your own bitcoin conventions don't accept payments in bitcoin.  Big confidence builder there.

Rampant scamming.

Bitcoins can be and often are permanently lost.

Using an exchange, bitcoins are not anonymous, they are linked to your bank account and can easily be traced back to it.

MtGox is just a repurposed Magic: The Gathering trading card website.  Magic: The Gathering Online Exchange.  This is entirely ignored.

Bitcoin adherents generally won't accept any criticism, no matter how valid. It's like watching a cat trying to bury his shit in a bathtub, funny, yet sad.  Any differing opinion is regarded as trolling.  This is so bad, even after solid legal evidence of Bruce's scamming, he was still widely defended here.

I will say, though, that as a piece of software, Bitcoin is pretty solid.  The community just sucks, though.  You guys need to stop labeling everyone who disagrees with you as trolls.  You make a lot of noise about the free exchange of ideas, but you sure as hell don't really believe it.
