Inspired by this (https://www.ycombinator.com/library/L3-does-your-startup-website-pass-the-first-impression-test) and this (https://www.reddit.com/r/calvinandhobbes/comments/14fljbq/frank_appraisal_of_your_looks/) I offer to do the the following for FREE:
* You send your landing page URL to me (email in HN signature)
* I will spend 15 minutes max exploring your website while recording my screen with audio
* I will then make the video and my comments available to you
I have more than a decade of product experience, though am no UI design expert, so I'll assess it more from a general usability and product information sense.
