so github lets you leave comments on commits, pull requests, issues, etc.
i think they should let you leave comments on code. then they can have an IDE plugin that shows the comments. and also you should earn some sort of redeemable points for writing comments.
so if you're trying to understand something like player.flags ^= (has_mp3() ? FLAG_MP3 : FLAG_OGG), you can hover over the ๐ฌ icon and see that SourceCodeWizzzard2005 said "i think this is something to do with music? idk" and RonaldGustaffson said "This is some codes that makes to have MP3 play back on all of the Linux systems and Linux systems, but not Orc Vorpis on an Windows computers systems."
