It's been a long time since I posted a list of boards I think are worthy of many people's attention. Here's the list I originally shared, with a bunch of additions. It's by no means comprehensive, but perhaps you'll stumble upon a few interesting nooks or crannies. (Some of these boards are woefully neglected -- if so and they're for a topic you're interested in, post a message or two anyway, as it might help attract more readers. For every new board to thrive, it needs a few people to take a chance and start a discussion.)

WARNING: This is a VERY long list. One good strategy might be to scan through it, clicking in and out of various boards. When you click into a promising board, click the red heart to make it one of your favorite boards. Then you can go back later to read through it at your convenience and see if you like it. If you don't, remove it from your favorites. If you like it, leave it there and see what conversations develop in the future. Keeping it as a favorite will remind you to drop in now and then.

Apologies in advance for the hundreds of interesting boards I've neglected to list. Feel free to list more!
