I made a small donation, and if you like it here, I think you should (if you can) too.
I am one of many that have sought out alternatives to Reddit. I really like the feel of how this community works. I've not seen them push the need for support, but I'm sure they're feeling it. It's clear they've made changes in the past couple of days to help support the growth & load.
That said, servers and bandwidth aren't free, and they've seen a massive wave of influx.
