See, according to how you defined the values on your scale, I guess I'd be a five - but without your definitions, I would have voted three, assuming that a five stands for someone who hacks into NORAD...
As for the user-friendliness of the community developed apps, there's definitely some room for improvement. If nothing else, some of the wording in the various installation instructions could be streamlined; different people use words differently etc...
(This is something I have experience with and would happily volunteer for if only I had more time ... well, maybe when the kids are off to college ...

Plus, I'm not sure if links in developer's messages should lead directly to the download - how about they lead to the Wiki entry and the download starts from there? There are apps out there where there's one download link for the original port, one for the upgrade, one for a required library, one for the Aztec language pack ... well, I exaggerate, but you know what I mean. This can be very confusing to clueless people like me. Should be all in one place.
