Simple answet for that.. Because none of them know anything about those protocols and won't bother to setup anything like that just so thry can talk to me.. Because it's also too "complicated" for them.. You do understand that the majority of people aren't as tech savvy as you and I.. Anyways ur right it's getting out of hand with the off-topic this was my last about this particular subject.. EDIT: My point exactly ..
You guys are aware that whatsapp is tool for it's company seeking for phonebooks, complete userdata, like including addresses, email and birthdays is what they want. Jabber/XMPP was behind most or even close to all new garbage msg apps... they use what is already there... we should start msg.maemo.org and jump the bandwagon. @bandora ... "you install skype, you register for skype, you login, you add friends, you call" "you install a jabber client, you register a jabber account, you login, you add friends, you call" What is the difference? - One is a company reading your texts (they ping any https URL you write btw) and listening to your calls, one is an admin respecting your privacy... you are here on a tech savvy forum... XMPP is the protocol behind jabber, facebook-chat and many others - used to be googleTalk yada yada yada (bad tongues say skype uses the code as well) don't know about whatsapp but I doubt it is not XMPP even n900's yet old jabber client supports voip... we tried it 4-5 days after we got our devices... Skype on a phone is nice to have but skype's netcode is so bad that it is a real battery drainer...
