Should registration with Woot be required to purchase a product?
This question resulted when I clicked on a deal posted here, and then saw purchasing required registration.
It's pretty well known that requiring registration to purchase a product (and not allowing "checkout as a guest" or some such) inhibits purchase. See, for example: http://www.uie.com/articles/three_hund_million_button/.
It's a question of usability. Even if it's easy to circumvent, it's still a disincentive for many users.
Now Woot is unique in some ways. They allow login through Google and Facebook already, which covers most potential buyers. They also make a notable attempt to foster community, and registration is vital for that.
However, I submit that a numerous people have bought from Woot but never participated in the community. And many other users may be reluctant to use logins for other sites at random online shops.
Is there a large segment of the population that Woot loses as potential customers by not having the simple option to "Checkout as a Guest"?
