If this is Friday, I must be in Sydney

I am briefly back from internetless visits to family in Victoria (my home state), and shortly to fly out to Lisbon where I am to give two talks I have yet to finish writing (of course! Not to worry, I always do this). In the interim I must proof my book and do a thousand things. Once all this is done I promise to put some substance online here. Very possibly my talk on trees (yes, there's a slew more to come).

Meanwhile, talk amongst yourselves.
