sure I learn a lot from people sharing as well - and try to share too - but I do see a difference in charging people a few bucks for telling them things they will find in blogs and trumpetting my "success" story - and reading a blog post from someone sharing a good insight. Sorry if I'm being harsh here - but we do have a bit of a pat on the back community here - however I realize that might not have been the most constructive comment. So heres some more constructive advice - its great that you got a bunch of beta signups. Build your product - that will be worth a lot more than an ebook about how to build a landing page that will get you more signups. There are plenty of people out there with significant experience in this space who publish tonnes of great free content weekly about these things - a lot of it backed up by research too (ref: copyhackers.com). Same thing with marketing related advice - check out the blogs of hubspot and kissmetrics for example. If I were you - rather than spending time writing an ebook and trying to sell that - I would use that content - publish it on my products blog - and use that to drive traffic to my product. Ref: content marketing. Just my 2 bits - the industry doesnt work that way - people buy content from those who have had considerably larger successes - but prove me wrong on this and I'm the happiest guy around :D - it would be an indication for me to go publish a whole lot of ebooks that I didnt think would ever sell!
