Please consider allowing scanning tarball/zip distributions of source directly as well. It is a SCM-agnostic method that is also well-supported by GitHub, Gitiles, hgweb, and many old but still-in-use projects that pre-date Git.
It would be nice if this could be mentioned a bit clearer in the blog post and/or README; it's not really that obvious at all and I had to go to the source to check, and loads of people here seem confused about it since it more or less implies "we looked at all open source projects".
The issue with the mirror is we don't get the important stats to make decisions. E.g. number of contributors, issue changes due to custom issue tracker. We are still thinking on how to add information from such cases in automated fashion, ideas welcome!
The main Go SQLite3 for accessing SQLite databases is in the top "C" list.
But SQLite itself doesn't seem to be included in any of them. o_O
