I love email. This is the most consistent and reliable way to reach me. My email address is:
benratkey [AT] gmail [DOT] com
If you send a message there, I will definitely see it (as long as it doesn't get caught by a spam filter). I usually reply to personal emails within a day or two.
Twitter is usually a good way to reach me. My Twitter handle is @BenRatkaj.
Sometimes, I take breaks from Twitter and completely log out from my account for a week or more. You can look at my recent tweets to check whether I'm currently on a break.
This is the contact method with the lowest latency; I respond pretty quickly to text messages.
You can have my phone number if we're friends. Just ask!
I don't spend much time hanging out on Discord, but if you DM me there I will probably see your message.
You can become friends with me on Discord by connecting with me through another channel first.
These are not good ways to contact me.
