Yes. Don't be afraid to post your real URL here. A TinyURL looks unprofessional, shady and gives the impression that you're not quite sure about the success of your startup.
I have made legitimate changes to the site as a direct result of the initial feedback I got here. I simply want to see if the people that looked the first time like the changes I have made and have any more feedback.
How else should I do this?
Any more is overdoing it.
I see many requests for feedback that appear to be early in a site's lifecycle. Might it not make more sense for HN to just allow you to repost a URL after a certain amount of time has elapsed? It could even add something to the title indicating it's the n-th request for feedback. Start-ups are an iterative process so to only get feedback one time is a bit short-sighted, isn't it?
Is there another site that provides something like this? If not, maybe that's something else I should create! :-)
