But I think it's too early to call roam, the startup, a success. It has some mindshare, but the product has no defensibility. It's not that complex. A competent developer can probably build a clone of Roam in 1-2 months of full-time work. A lot of copycats have started already and I wouldn't be surprised if in a few years it's not Roam that has won but just another copycat that had a better UI. Kind of reminds of how Slack killed that other app before it... was it... hipchat?

The takeout option lets you download a copy of your files at any time but they also often have sync issues, etc. As far as I can tell, they make heavy use of local browser storage which syncs to a cloud back up. People keep seeing data loss (or did when I stopped following them) when this connection fails. Is it growing pains? Yes, probably. Is it right for me when this risk can lead to data loss and not just a conflict resolution process? No.

I do wish them luck and am looking forward to the various local clones getting better (org-roam, Obsidian, etc... no shortage).

Personally I'm not a fan of the company, culture, and the cult-like following Roam has. I hope somebody else succeeds and takes over the market and I'll move there. But so far roam is the best life/knowledge management app I've used, and I've tried a lot of them.
