If you find (or build) anything like that, I'm sure HN would love it. Personally, I'm concerned about my favorite reference manager, Qiqqa, which was open sourced when retired by the company that made it. As far as I can tell, there is 1 (maybe 2) coders maintaining and improving the software and maybe a few people catching and reporting bugs. It seems like a razor's edge, but the most active contributor is doing a great job. It would be interesting to see different projects succeeding and where others stagnated or fell apart.
Of course not. I'm a little confused as to how you might think that if the case. I use it daily, and I'm invested in its continued improvement. I ask because I'd like to know how projects best succeed in the kind of situation.
