There was nothing groundbreaking about Slack, and there still isn't. There are a lot of naysayers on HN scoffing at Slack for basically being a worse form of IRC, which is silly and wrong, but also right in that there is nothing groundbreaking about the tech. But products don't need to be groundbreaking to win. They just need to be better than the rest, and perhaps generate the necessary "reality distortion field" that convinces people that it's the next natural evolutionary step. Once you convince people of that, they don't go back to HipChat.
I was at a startup, we used a mix of Hipchat (business types) and IRC (developers). A marketing/social media guy who was buddies with Stewart joined and insisted we should all switch to this, and there we were, dogfooding Slack (this was closed beta days).
Hard to beat free user acquisition.
You could try and cobble together something similar from an IRC server plus ten different programs, but most companie would rather pay Slack a wee amount than maintain a Frankenstein's monster.
Mobile applications with notifications, conversation threads with +draft/reply (IRCv3 draft), multimedia attachments (IRCv3 idea), authentication with SASL and standardized account management (IRCv3 draft), etc.
Look at what IRCCloud provides, and what IRCv3 is doing.
That's what normal people see when they read your message.
Even if you want to self-host, there are solutions — get any server, run
docker run \
-v /path/to/folder/where/you/want/to/store/the/config:/config \
k8r.eu/justjanne/quassel-docker:v0.13.1
and connect with quassel or quasseldroid to that server (the setup wizard guides you through everything else). It's about as simple as it can get for selfhosted. (Quassel gets you message retention and search immediately, and the other features are already being worked on).Uber is still making losses in almost all markets it’s active in. Slack is making a 380'000 $ loss per day. Amazon hasn’t made a profit a single time in their entire history.
The Silicon Valley model of "let’s gain a monopoly by giving away a product and outspending everyone on advertising, then monetizing it" doesn’t reward the best product. Never has, never will.
And companies grown the traditional, honest way, making actual profits of course can’t compete with that. If I opened up a supermarket giving away everything for free, of course I’d have more customers than the supermarkets who have to make money.
But it was never too much in the red. It shouldn't be placed together with Uber.
Stay up? I was at a company that was on Hipchat, and we really liked it, but the amount of downtime got to be semi-unbearable. We switched to Slack and it had much better uptime.
