I love experimenting with text editors and occasionally IDEs. In the last 6 months I've used no less than 5 different ones... each time I learn just how valuable Vim is to me.
I like building things and sharing my experiences. I've mostly focused on the web, but of late I've moved a bit more towards back-end systems and databases. I also love working with Audio/Video.
I think sharing what you do is incredibly important; equally as important is to make sure you never posture as an expert unless you truly are.
