(Strictly technical details at Github, otherwise it's all over the map and impossible to follow. General discussion here at the mailing list is ok.)
I hear your concerns and I agree, it's a great pity. It's an issue I think requires more work and attention than any bug out there.
For the background: me (Mikael), Philipp and Kasper have been pretty much the only people active with the development of the site. A year ago Rémi and Olexandr helped out for a couple of months to create the new version, which we didn't manage to finish year ago with the time we had. More about that below.
We're all extremely busy people and Hitchwiki has been lower and lower at our priorities over the years, sadly. From volunteer projects
https://www.trustroots.org/ is currently my top priority, but I also have to make a living somehow. (Would be great if that living would come trough these projects.)
I've been asking around for more volunteers for a while now and thinking how to make it easier for people to hop in. I've also directly asked a bunch of people if they would like to take lead responsibility, but no dice so far. Hitchwiki's structure isn't the most sexiest out there to work on (it's PHP, MediaWiki is quite of a monster and things are generally hard to make look/function great device wise.)
That new hitchwiki that I mentioned is nagging in my mind all the time and I (and the rest of the team) really wants to get it out. It would fix a lot of issues (esp. at mobile front) at once and lay out much easier bunch of code for anyone to continue development. I've been busy, new stuff has kept appearing requiring my attention and I've been postponing in all the summer/autumn/winter. It would require me sitting down for like a half week/week to work on it.
Currently my todo list for this stuff looks very promising and I'm pretty confident we can publish the new version out this winter.
However, when it comes to daily fixing/maintenance, it still falls trough our priorities. We need new pro-active and self organised devs really badly. I think I'll roll out a small campaign for that soon. Other ideas welcome as well!
