Tipping (if you found my posts useful)
I put coding tips and tutorials on my blog for free so that they can reach anyone who might find them useful! These blog posts do take a non-negligible amount of time to write. If my work has helped you in any way, I will happily accept a small tip if you have the financial resources.
I used to post about stats/science on occasion @monica_too_, but I have stepped away from Twitter since it was taken private. :(
