Looking for like-minded people to discuss programming, gaming, writing, or any other interest? Hamster Pad will help you find a Slack community to join.
The site essentially aggregates open Slack teams. Create an account on Hamster Pad, click on a chat and you'll get an email invite to join the Slack team. The tags for each chat help you figure out if it fits your interests, but currently there's no search or other way of filtering the communities list.
As of this writing, there are several Slack teams dedicated to programming and particular programming languages, but there are also teams for general topics such as music, travel, and Star Wars.
Whether you're feeling lonely or want to join a new Slack group, Hamster Pad could help you get connected.
