This may have some potential, if you can get traffic. It's a bit sluggish though (for example, the render + chart feels a but slow)

Ya it's a base project (I have a lot of ideas) unless traffic comes, but I feel like that'll be impossible. I have a full time job and kids so have zero time to work on side projects:( If more traffic I'll put more addons otherwise I guess it's dead in the water.

To your note I'll have to load more than 1 question + charts (maybe 5 in queue). BTW thanks for adding a question to the site:)

I didn't see a link. Could you include it ?

I took a look, but how do you compare yourself to existing players like meetup.com ?

Well, the idea took shape when a few people at my work place wanted to form a private group of marathon training group, but didn't want to use work emails or meetup.com as it was too expensive for such a casual group. That's when I realize that there is an audience for casual interest groups where people just want to communicate through threads in a conversation and not worry too much about maintaining it.
