To the extent you're describing a decentralized reputation aggregation
system, sure, I think something like this is possible and really
desirable! I think a key point is that it's nonsensical to have an
'absolute' or 'public' reputation, as that is easy to be sybil
attacked. Instead, something like Bitcoin-OTC's trust-graphs, where
inferred trust is a measure between a *pair* of people rather, is
promising. Lets continue talking about this! This is what the future
of markets will consist of.

Well like most centralized systems, everything runs great and
efficiently until it fails catastrophically. Possible outcomes for
Bitmit (and silkroad for that matter) are: administrator runs away (or
gets "hacked") with all the bitcoins in accounts at the time, or
spammers could start to rake in more money by inflating reputations
for a fee.

Shouldn't the goal be to build infrastructure to replace such brittle
centralized markets with more robust decentralized ones, much as
Bitcoin is infrastructure for replacing brittle centralized payments?
