No. It’s not wrong. Is Bob your personal friend? It sounds like you are only ex-coworkers. Getting in touch with ex-coworkers to find work is what business networks are largely about.

What do you mainly use that supports tables?

I migrated from mediawiki to markdown in git 8 years ago and never looked back. The ability to publish to any number of static site hosts, and use any number of editors, some that have preview mode, is rad. Data liberty, data portability, wide support, easy to convert, easy to grep, good enough for 95% of written notes.

My biggest gripe is poor support for tables of data.
