Yet another person complaining about gox being made of cardboard; yet still using gox
You may not know it, but Gox unfortunately is the only service around here that didn't run with client's money in the last three years, and that matters more than poor service. However, only up to some limit
This +1
plus, even more, there is simply no alternative to Mt.Gox, when you combine the high volume, the relatively easy availability from any point of the world, the ubiquitous API used by most other services, and the USD/BTC rate, which, due to this dominance, is commonly used as just "the" Bitcoin rate.
And yes, this is a very dangerous situation for the XBT economy as a whole.
All of those advantages, besides the API, are caused by the volume. If that volume were to move, the advantages would follow, but it is a chicken and egg problem. Like I've said before, we will likely have to see MtGox broken before we can have 10 replacements pop up and really allow bitcoin to grow. Many of these future leaders are already with us, but are waiting for the opportunity. Right now, MtGox and it's shitty reliability are the biggest thing holding back bitcoin.
Edit: And many other exchanges offer solid APIs.
