Try. * I create a trello board and divide my ideas into a few categories (do-able, I really like, this-is-ridiculous, already-existsi-so-who-am-i-kidding etc) Then... (maybe)... * Create a landing page for each one of them (ok so maybe not for all of 118!!!) - launchrock * Post on HN, Reddit * Collect the email addresses & feedback (ask them questions or survey when they sign up) * Email them back on each of your idea and ask for further feedback (but don't spam) Above exercise might take you 2-3 weeks. But I find it a practical way of learning - and I think the often more interesting thing is that you learn to "change" your idea depending on the feedback.
