Repositories of external software, may be of varying quality of use, my be available for only some hardware configurations and platforms, and some versions of Ubuntu.
A list of new Repos could be collated (users suggestions/recommendations for use or avoidance)(and Repos that are not listed in synaptic).
These could categorized by performance and reliability, platforms, and Ubuntu versions.
With comment section for discussion of issues.
New program developers could also submit their repos there.
There could be a section of the Ubuntu web site for discussions and sharing of information on programs used by Ubuntu users, which are not in the current Ubuntu repositories.
This section would be where people who are looking for additional software could go a find some good tips, hints, pointers as to where else to go and what to look out for.
Plus programs in this section that are found to work well with Ubuntu, might then make it onto the Ubuntu Repository, and maybe into an Ubuntu distro.
