20 Telegram Alternatives to Chat With in 2024
Slack works more like a forum than Teams does – falling somewhere in between a forum and a chat software. It lets you organize discussions into different channels, as well as by thread. You can invite others into a thread by @mentioning them, and it lets you add lots of different types of content. Slack works really well for 1:1 audio meetings, “huddles,” that give you the...
Why we switched to Mattermost
Now, obviously core messaging functionality is critical. Mattermost is great there, but so is Slack. In fact, Slack features like third-party integrations and threaded messaging were missed greatly (thank you, Mattermost, for recently adding threaded messaging). So the relative parity between the solutions from a ‘speeds and feeds’ perspective was table stakes, but we...

Microsoft Teams Vs Clariti: Which one should you choose?
The main reason behind the sudden rise of Teams is it is being offered at no added cost to Office 365 users. This strategy paid for Teams as it was able to increase its market share and overtake its potential rival Slack in no time. Though Microsoft is not earning any revenue (they may actually be losing money in selling Teams), they are able to sustain due to their deep...

  • What are you shocked people are still doing nowadays?
    Signal works the same but without the user tracking from Meta/Facebook. Many people use it as well but I'm surprised that a majority sticks to WhatsApp. Source: 5 months ago
  • A Practical Guide For Safety And Reporting Crimes For Our Community
    A question I often get is "Well are my text messages safe" The short answer is... Maybe? Depends on what type of phone you use, your carrier, and a bunch of other factors. One way to avoid this is to use an end-to-end encrypted text service like Signal if that is a concern of yours. VERY IMPORTANT NOTES: Telegram and WhatsApp are not secure.

  • Signal Public Username Testing (Staging Environment)
    The linked page is on signalusers.org, but Signal's regular home site is https://signal.org/. I'm looking all over signal.org for some link from there to signalusers.org, as that would make me more relaxed about the authenticity of the latter -- i.e., that it really is run by the same people who run signal.org. Yes, maybe I'm being paranoid. But we're talking about an app whose whole purpose is secure... - Source: Hacker News / 6 months ago

Set up an account in each app and start leveraging the text, photo, phone and video features to have easy and fast conversations with your global contacts. See https://signal.org...
