Plussers, I’m now at https://plus.google.com/+MarkShuttleworthCanonical/ and quite enjoying the service. That G+ persona is mostly software and cloud related (so short on beekeeping, kitesurfing or botanical pursuits).
This is probably the best way to keep in touch. I’m not on Facebook and every year Claire and I clear out the oddball fake-me’s that seem to crop up regularly there. To their credit, FB have been really good about sorting those out. I’m told I’m missing out but, srsly, TIME!
G+ seems really clean and well organised, the chatter is mostly thoughtful and good-natured.
