Only ever used MSN occasionally as this was the pre-smartphone era when I had to be physically sat in front of a computer to use it. Post-millennium I had the nursery slope of WAP phones which had dedicated mobile-friendly social pages (Mopilot for instance) and it's staggering to think something once so futuristic is now decidedly retro... O'course, nowadays I'm all about yer Twitter, with longer screeds dumped elsewhere (DS for one), but it'd be nice to have some sort of one-on-one conversation function back...
