@davemorin we're trying to find the right balance. Some people want to discover and signup for pre-launch products if it's something notable like Foursquare's Swarm; however, that's subjective. We're revising the FAQ now to clarify what's encouraged and will be labeling launched vs. pre-launch products to set peoples' expectations before clicking through.
In this particular case, they don't provide much information at all or even a form to subscribe via email for updates, which seems odd.
@rrhoover@davemorin It's tough to find the balance as a PH user too. I've purposefully not posted pre-launch startups before, only to have someone else "beat me to punch". For Opendoor, if I didn't post it, my guess is somebody else would have.
In this case, I used the Techcrunch post as a guide - while they don't have a product to speak of yet, there might be some interesting discussion from the PH community on how they've structured fund raising for example.
