Case in point:
The following proposals are both music related.
Reading through the comments on these proposals you can see that there are a lot of arguments for merging these two proposals together.
Merging them would increase the likelihood of one of them reaching beta and create a larger single user base rather than two smaller ones. The tagging system is more than enough to separate instruments, musical styles, etcetera; so for a question related to an amplified guitar you would have tags [guitar] [electric] and so on.
Is there a process in place for allowing the merging of similar Stack Exchange proposals (including followers, etc.)? Or is there anything like this being planned? If not, why not?
