I regularly (at least once a week, sometimes multiple times per day) BBM'd the Bloomberg helpdesk with notifications that their data was wrong. This varied across many of our needs, but even simple stuff like money supply / macro stats was often just wrong. How had no one spotted this before? We ended up just using Datastream terminal for macro data.
Killer feature is Excel plugins. Do you have plans for this?
Edit: Just tried Quandl didn't know about this before. What a fantastic tool.
