I think the problem with that project is that there is no rush to crunch backlog. If you focus on everything in “Stormy weather” you may feel pressured to rush, and I know you left a message on the project saying there is no rush. I think a bit of backlog does no harm to the project. The purpose of viewing how much backlog there is is so you can see how long you think it will take. For hundreds of thousands of questions, it may take about two seconds per question. Assuming no loading time, it will take (184092*2)/60/60/2 days assuming you are willing to spend max two hours per day on this backlog, which is almost 60 days. Loading times may bring this number up to almost an entire year. I think it would be best if we just have the backlog be crunched whenever someone feels like it, instead of organizing a project dedicated to just crunching backlog.
If you want the project page that you created deleted, you can maybe ask @Galactic-Radiance
or @JayneG
for guidance. I appreciate your efforts, though, to try to make wikiHow a better place, but there is no need to make projects on reducing backlogs.
