I am really enjoying using Lighthouse for managing a couple of projects that I am working on. And I also really love using Github to manage the source code. These services are so great that I am thinking of setting up accounts with both for my clients in the future.
From reading the Lighthouse and Github blogs, along with the general webosphere buzz, I get the impression that many others are as pleased with this combination as I am. So my suggestion is to team up with Logical Awesome to offer a Lighthouse + Github package deal. That way, users of either service by itself would be more tempted to adopt the other. Or at least I would appreciate it!
