If you're looking to contact me about something I wrote that you found on the web, you should contact the site where it's posted. Publications generally don't give their previous authors and employees unfettered edit access! Maybe look up where I work currently before emailing me?
If you email me at my personal address to "update" an old article, or pitch a product or crowdfunded item, I'm likely going to report your email as spam and block you.
If your email is actually about this site, or something personal, that address is ks{last name} {at} {gmail.com}
Otherwise, you might try me on Twitter.
I have a PGP key pair for discussing sensitive or confidential matters. This is my public key.
See something not quite right with this site? Create or solve an issue on the open-source code, or jump right in and make a branch. I'm always learning.
