During my time at the *Signpost*, there were large fluctuations in the supply of people who had the time, willingness, and skills to write regular features for the *Signpost* and work on the publication process. As far as I know, the labor supply is still the biggest problem. The discussion on https://en.wikipedia.org/wiki/Wikipedia_talk:Wikipedia_Signpost supports that view, although there is also some discussion about technical problems with the publication process.
I think that the labor supply problem could be partially addressed by making at least some Signpost work into part-time paid work.
However, I'm not sure that anyone with the required financial resources would be willing to fund this work. I think that is the biggest step that would need to be addressed.
If work on the *Signpost* isn't funded and if volunteer availability continues to be limited at best, then unfortunately the *Signpost* may become a shadow of its former self, or fade into memory indefinitely. I would be sorry to see either of those outcomes. I think that the *Signpost* performed a valuable community service as a reliable weekly or semi-weekly publication with a variety of informative and interesting content.
