Why a chuckle? I like that they at least let you fill out the CLA online. The ASF still requires contributors to fax in a paper form (or they did last time I checked, which was when I did mine, which was, now that I think about it, some time ago, so maybe this long rambling comment is actually pointless after all...)
Anyway, the point is, having an online form to submit a CLA seems like a positive step to me, if you're going to require CLAs at all. And a CLA that simply grants a perpetual, worldwide, irrevockable license to the content, as opposed to asking for a transfer of copyright ownership, doesn't seem to onerous to me. And for an Open Source project with commercial backing it is pretty commonplace.
That said, we are an Open Source startup, and we don't (currently) plan to ask for a CLA from outside contributors, but just something basically saying "I license my contribution under the Apache License v2".
