I've decided to stop putting it off and jump right in.
I posted a few months ago asking if there would be any desire for such a social platform, on which I had a lot of wonderful feedback from you guys. So I thought I'd write this post to let anyone that's interested know that it is being built, and you're welcome to lend a hand!
This is an amazing idea. I've toyed with the idea of creating both subject specific and geographic specific groups for my interests but it's a clunky solution. For example, I like birdwatching, but I want to know what people are seeing around me, not on a continent away, so being able to join a centralized 'birding' group then narrow it down geographically would solve the problem of having to create potentially hundreds of sub groups. Same for politics, news, restaurants, etc.
Thanks for this! 😃 I have been going back and forth on the idea of providing the end user with the ability to create their own categories. I was wondering whether it would be better to have an Other type category which the admin can react to and create categories as needed, but your post has pushed me back to the idea of allowing category creation. I think if I do implement that, I'll have a switch for it, so that the instance admin can choose.
