Welcome to the Construct community, hero_bash!
Yeah, most of the traffic we get seems to be from Stumble and other link sharing systems. The project is very, very young, and for now this sort of word-of-mouth is preferable to costly advertisements. Also, another side effect to this is the people here are of the type that passionately analyze and debug the thing instead of spamming the forum with 'why beta crash on meh u guys suxx0rz!' Seriously, in the 3 or so weeks I've been here I've seen the fastest development and feature buildup of any project I can remember being part of.
So yeah, keep lots of backups and feel free to join in as everyone comes together to make sure the v1.0 is the best it can be. Please be sure to show us what you come up with as well.
