Thanks so much! About the frontend comment - I'd not really heard anything about the actual design, so that's a very welcome piece of feedback - I'll add that to the bugfix list.
I think half the reason I really built this app is because I keep saying on my own Twitter "I want to learn how to do ____ - but I don't know where to start!". When I don't hear anything back, it's a little bit demotivating. I really love the idea of strangers helping strangers with their work and goals too; but I also feel that the questions would be better suited to those who have specified exactly what kind of questions they can answer.
Food for thought, I guess. Thanks so much for your feedback, I really appreciate it :)
