For work, we use Notion. All our tasks are in a Kanban view called "Priorities". In Notion, every task is also a page, and this gives us a lot of flexibility. We also use things like tags and statuses. I haven't found anything as flexible as Notion. Can't recommend it enough.
For personal tasks like doing laundry and buying eggs, I use TeuxDeux. I like that it carries incomplete tasks over to the next day, and the product is otherwise dead simple.
#empathy is where we post screenshots, articles, or quotes from customers or prospects talking about their challenges. These challenges don't have to have anything to do with us or our product. Feeling what our customers feel is an important part of our creative process.
#log-leads is where we manage all of our inbound. Each type of inbound (early access request, signup, free api key request, contact sales) goes to this channel, and we can send automated responses to the inbound based on the emoji reaction.
Example: Free API key request posts to this channel with some details on the request, we react to the post with the :whitecheckmark: emoji, which triggers a Zap that cuts them an API key and emails it to them along with our "Getting Started" docs.
