I consider myself a novice Git user. I can debug a merge conflict okay, but don't know the more esoteric functions like `blame` and others. I merged someone's code into mine on GitHub the other day, and they were mixing spaces with tabs in the code, and I'm a tabs-only coder, so I resorted to simple issue-filing where people want x feature or y bug to be fixed, and I fix it myself, rather than weird merges happening.
