As part of a registration form I am building I need to, at some point, differentiate between whether the user is a 'student' or 'professor'. I've seen this handled in two different ways and was curious if anyone had any thoughts or research on the benefits/downsides of each way.
Two separate sign-up buttons on homepage
www.lore.com and www.piazza.com
One sign-up button, then two choices as part of the sign-up flow
The first method is one less click for the user but can potentially make the homepage more confusing with two call to action buttons next to each other. Also, with the first method, you couldn't just have a single 'sign-up' button elsewhere on the site, you'd have to provide two 'sign-up' options at all times.
