Some who saw 2017’s mini Twitter exodus happening dismissed it as a passing fad, while others dissed Mastodon as a dead-end social network doomed to extinction just like its eponymous megafauna. But the thing is, as long as administrators are paying to maintain their instances, Mastodon can expand or contract naturally without threatening the entire network. Because it's open-source, you could even start your own if you were so inclined. There's a main instance—, that seems to be the default for newbs like myself, so my new handle is

SteamZoo has long been touted as a great—if not better-alternative to Instagram, partially because of the way it turns editing and sharing your photos into more of a social game that's addictive to play.

The best replacement is a password manager, which can store your credentials for every site you use in one place. It can also generate a new, secure password every time you sign up for a new website or service.

MeWe bills itself as the ad-free, spyware-free, and censorship-free social network. Share your photos, videos, voice messages, GIFs, memes, and more to just one person, a specific group, or all your contacts. You can also send people disappearing GIFs and photos. Either way, MeWe won't track you. If you want to send end-to-end encrypted chats, however, it'll cost you 99 cents per month or $5.99 per year.

Last year, after Twitter began moving away from a purely chronological feed, Rochko began building the back end for what would become Mastodon. Instead of building a unified service, Rochko envisioned something more like email, or RSS: a distributed system that lets you send public messages to anyone who follows you on the service. Anyone can create a server and host their own instance of Mastodon, and Mastodon works in the background to connect them. (source)
@Corvin Adkins: I completely agree. My team and I use Podio and the internal chat is useful for general communication. And even though it integrates with Slack, I don't want my team to have to switch between apps to chat. It would be counter productive. We would love to migrate to Clickup but wouldn't be able to until it had the current features that our team is using on Podio at minimum.
