The contact prefix makes it clear that it's a contact and keeps them
grouped alphabetically.
Without it, one can wonder what diaspora is or difficultly find contacts
in a long tag list.
Also, contact:website is not exactly the same as website which could
contain no contacts at all.

It's similar to, for example, bicycle=yes.
Many persons use it meaninglessly, not as a override of a restriction.
They probably didn't read the documentation and they tag similarly to
what they see.
They probably believe that it means a road nice for biking or with a
cycle lane.
If we used the full form *access:bicycle=yes*, as Conditional
<http://wiki.openstreetmap.org/wiki/Conditional_restrictions> explains,
the meaning would be clearer and the mistake would probably be avoided.
