A recent thread about a similar product: https://news.ycombinator.com/item?id=24004588 Personally, I think just those limits make this a non-starter for me. 30 resources per topic over 250 topics is a total of just 7.5k links, which is nothing. Charging $19.99 a year for that (and that's introductory pricing!) is insanity, especially when there's free bookmarking tools, some of which are even open source or self host…
I'm working on yet another alternative, which we're about to launch: https://www.tefter.io/teams/free-trial We charge 39$/month flat, no limitations on the number of users, links, lists. The domain of bookmarking is definitely crowded, but we're focusing providing a solution where you forget you're dealing with bookmarks. With our browser extension, you can quickly jump between tabs, search you history and bookmarks…
Um wow. Does anyone actually pay that price?
