As GeneralAntilles has said, the answer to this is simple, and us "seniors" have been advocating it for ages: if the software you want to download isn't in maemo extras (or, for not quite release-level quality) extras-devel, don't moan at us. Moan at the application authors who don't care about your experience enough to upload the apps to extras.

Such authors may well perceive obstacles to extras uploading; if so, they should communicate them either here or on maemo-developers and steps will be taken to address them.

Interestingly, I know of many experienced tablet users (experience as in OS2005 770 users) who now only install one or two extra repos - including extras(-devel). You see, with experience comes the knowledge that it's not only identifying and installing all the extra repos (which gronmayer.com helped with), but the burnt fingers from conflicting versions of the same package in multiple repos.

It's not just users who the multitude of repos hurts: app authors end up duplicating each other's work, porting libraries that someone else has already packaged.
