I tried to post an iPhone but got stuck when I didn't post enough description. They emailed once reminding me but then that mail got buried and I forgot. They have an opportunity to fix that problem creatively, by maybe using different interfaces for different products, where each post screen is uniquely tailored to posting that specific product optimally.

They're definitely in the right path, but I think like any startup, they have some wrinkles to iron out. Luckily they have an amazing team and I think they'll do just fine in time.
