Check out the work done by Anaconda. They have put together a thriving business packaging and supporting Python packages for data science and machine learning, notably pandas, numpy, matplotlib, and their own package manager conda. They are beyond Tidelift, might even be seen as something of a competitor, except they don’t compensate their maintainers.
As for my own project pyparsing, I think I hit some of these, but could be better:
- online docs - at least basic documentation is generated from the source, and kept online at https://pyparsing-docs.readthedocs.io/en/latest/
- automated testing with CI (continuous integration) - done using TravisCI (CircleCI is another popular service)
- online tutorials / videos - I’m working on doing some videos soon; my project wiki (https://github.com/pyparsing/pyparsing/wiki) includes a page with links to articles and blog posts about interesting uses of pyparsing
- publications - I used to be more active in this area, including having a 64-page e-book from O’Reilly, plus articles in Python magazine; Julia Evans publishes some good zines at https://wizardzines.com/, and this medium seems very popular. Twitter activity is also good for keeping up visibility, as well as maintaining a sub-reddit, and both of these are free.
- conference presence / visibility - easier than this sounds, local meetups are always looking for speakers; state and national conferences may be more competitive to submit to, but keep trying
- logo - I have no logo, nor do I have a polished web site. I always thought that something like a reverse meat-grinder, taking raw data and producing parsed information, would be good, but it turns out this is very hard to actually convey visually
- swag - I added this thinking about another Twitterer I follow @kvlly (Kelly Vaughn), who has really done well producing stickers and mugs with git and regex cheat sheets, plus stickers. These would represent more cash outlay though, so approach with caution. If you do get a logo, go to a mall and get it embroidered onto a golf shirt and wear it to a software conference.
