The biggest item in my portfolio is xi-editor, and I confess I'm wrestling with some of the questions raised in this thread. I think it has the potential to be a serious player in the editor space, with extremely high performance goals (including fast startup and low RAM usage) yet a modern feel. It also has a great little open-source community around it who have been contributing significant features.
Yet it's at the point where it's _almost_ done enough to use for day-to-day editing, and I'm hesitating a bit before pushing it over the line. I think I'm scared of having lots of users. It's also the case that I'm very interested in the engine and the core of the UX, but the complete product needs a plugin ecosystem and along with that ways to discover, upgrade, and curate the plugins (including making sure they are trustworthy, lately a fairly significant concern). That's potentially a huge amount of work, and it doesn't really line up with my interests.
I'm wondering if it's possible to focus on the parts I care about and try to foster the community to take care of the rest, but I'm not quite sure how that would work.
If this were a business and I had some way of making a few coins from every user, then my incentives would be lined up to make the best overall product possible, including the less fun parts. But that's off the table; among other things, there are a number of good free editors out there, and the niche for a better but non-free editor is also well occupied.
Maybe the HN crowd has some ideas?
