As a 'user' I am very happy with the idea of having Alpha's, gives me a
feeling that there will be less chance of problems being released in the
final version.

Because not only does it give more chances to test, but might encourage
more people to get involved in contributing, either ideas for minor
tweaks or simple patches etc. (as being not quite finished, and an
expectation that minor functional changes have a possibility of being
accepted for the version, if there is sufficient merit).

Cheers,
