I think @patrick raised somewhere the point that it’s hard to discover/debug programming errors with the decentralized model because they happen at the user’s side.
Providing a good solution for analytics and debugging is probably a really important thing for Blockstack. Users should have a very low barrier for reporting errors to the developers (i.e. a popup with “The app just had an error. Want to report it? [Text box for additional information]”).
If we don’t provide a good and easy-to-use solution for this people might get back to “just including the already working Google Analytics suite”, which is probably a very bad thing for a new internet
