as long as they are still proven to pay, and have fast deposit access, I think that's enough.  I don't need any other new services before I confirm that.  however beliefs about the money they hold are very important.  take a look at a number of such sites, or exchangers that exist today, everyone sees whether the place is trusted first, before looking at other services.
if there are other services that can be helpful and useful, it will be another plus value.
