You clearly put a lot of effort into writing this blog post, creating the header image and sharing it across dozens of Lemmy communities and Github issues. I only wish you would put even a fraction of this effort into actually resolving some of the mentioned issues. After all you are a programmer and many of them are relatively easy to resolve with a bit of time.
What you dont seem to realize is that Lemmy only has two fulltime developers (Dessalines and me). We are both working every day to fix bugs and implement new features in Lemmy, but there are only so many hours in a day. Whenever we resolve one issue, a new one gets reported so its impossible to resolve all of them. The repos for lemmy and lemmy-ui currently have 750 issues. So there is no other way but to strictly prioritize what we work on, and ignore things we dont have time for. Obviously people will disagree with the exact priorities, that is inevitable.
The only solution is to get more contributors who help work through the issue backlog. Or if you are not willing to do that, switch to a different platform which is backed by venture capital and can pay dozens of developers to work on it.
