Google is about as good as it gets for translational abilities, AFAIK - and that still leaves much to be desired, in terms of it's transational abilities. I'm ignoring the security concerns of having everything you read/write travel through a third party that is mining user data. Translate.google.com doesn't even need a plugin/helper, either, it just works.
What about a technical support area? as in, not just browser-centric. Im sure there's more than browsers people have problems with - and I'm equally sure there's more than enough expertise kicking around to resolve said problems. As a community, we should be trying to make things better for each other where it's possible.
