Especially if you are at a remote-first company. What is the main communication tool/channel?

Is it Slack? meetings? email? Asana? a combination of these? another innovative way? How do you use your tools to manage discussions and communication?

I'm sick of using Slack as the main communication channel at my company. Many discussions get lost as new discussions appear. Threads are awful but sometimes necessary. Link previews are distracting. Etc. I feel we are misusing it.

We do meetings and emails of course, and Asana, but Slack is the main and most used thing.

I'm trying to find a way that's good for work-related discussions and at the same time provides some social element (we are fully remote, we need to feel the company is alive)

So, please share what you have!
