I agree with Wreck. I support efforts to get WhatsApp running on Maemo and our N900s, and I think it really shows the dedication and talent of this community to our devices.

It's easy to say if you want WhatsApp, just buy a new (Android/iPhone/WP7) phone or run NITDroid. But the fact is we don't want to do either of those things, we want it running natively in Maemo, so we don't have to compromise, change to a (inferior imho) closed-OS phone, or have to reboot every time to make a phone call.

I would love it if there was a free, open-source messaging app on all devices that everyone used. But the fact is WhatsApp seems to be the market leader and due to the developer is unavailable on our phones.

I would love to have WhatsApp on my N900 so I can keep it touch easier with friends and get them to stop nagging me about changing phones since I'm not giving up my N900 anytime soon!

Best of luck to all the developers here who are working on making it happen!
