I'm a technical product/project manager by day and a hobby programmer by night. Things like writing documentation, triaging issues, coordinating teams, and planning releases is my bread and butter. I'd like the idea of spending time on an OSS project(s) that I find interesting, but I wonder if this is the kind of thing that would be welcome or even considered helpful. OSS projects are passion projects, and it feels like trying to help out uninvited with management tasks would come across as asserting ownership.
I do try to contribute what I can, but they're small hit and runs -- update deprecated information in documentation or add some examples, add more information to bug reports, etc., but I'd like to do more. Just without offending anyone :)
