If is best to start with email to bob@summerwill.net.

If you are following up about some prior contact (meeting at a conference, talking on Telegram, exchanging tweets, etc) please refer to that context in your email so that I remember who you are.

When we have established a connection, this is my preference order for communications software:

1. Signal – bobsummerwill.01 – E2EE text, voice or video
2. email – bob@summerwill.net (no PGP)
3. Telegram (bobsummerwill) – public groups, regular and secret chats
4. Twitter (@bobsummerwill) – public tweets (I do not read DMs from people I do not follow)
5. LinkedIn (Bob Summerwill) – public networking and private DMs.
6. Cell phone (text or voice)

With Signal being by far my preferred channel for all communication, given its strong end-to-end-encryption for text, attachments, audio and video formats.
