Slowest but most reliable. I read everything. Complex topics, collaboration proposals, bug reports that don't belong on GitHub.

All open source projects live here. Bug reports, pull requests, and issues get the fastest response out of anything. Best place for project-specific questions.

Mostly lurking. Occasional posts about android internals, security research, and things I found interesting. DMs are open but slow.

Active in a few Android and security-focused servers. Direct messages are open. Fastest for quick technical back-and-forth on something specific.

I check this occasionally. Professional inquiries, formal introductions. If it has to be LinkedIn — this is the one. Connection requests welcome.

Good for quick messages. I'm not always active here but notifications come through. Fine for short questions or sharing something interesting.

Mostly read-only. I post in r/androiddev, r/netsec, r/ReverseEngineering occasionally. DMs are hit or miss — email is better for direct contact.
