You're missing the point. If I email you, are we talking ON Gmail? ON Hotmail? Not really. We're using our different clients to interact with the same original message. Sure, the message gets converted to your emails specific formatting, but it's just a copy of the original info. The message itself is the conversation, the clients are just access to it.
You wouldn't say "I drove my Honda to the store". You'd say "I drove my car".
Nobody said "I'm browsing Apollo/Sync/RIF". You'd say "I'm browsing Reddit" or "fuck spez".
You're one step from being the mom that calls every video game system a "Nintendo".
