In my time on this forum I have been fortunate in having access to some pretty specialized knowledge. I now know a great deal more about chemistry, metallurgy, progressive rock, the manipulation of gas mixtures, interstate road rules, insurance, radar, lasers, etc, etc, (not that I knew much about these to start with). It occurs to me that we have a pretty good mix of expertise on this forum that encompasses and goes well beyond, motorcycles. I am interested to know where some of this knowledge comes from. I suspect we have some members with pretty diverse and interesting expertise to tap into when the need arises. How about a ‘who does what thread’? Strictly voluntary of course, as some people understandably just want to keep themselves to themselves. I don’t just mean old farts like myself with long careers behind them either, but youngsters just starting out as well. My stepson is an apprentice bricklayer and I am amazed at what I have learnt from him already. I’ll kick off myself and see who bites. I have a confusing sort of working life which divides into three distinct areas. 1. I still fly charter aircraft when the opportunity arises, to keep my skills (and ratings) current. This constitutes about 25% of my time. 2. I give flying instruction. Not so much these days ‘ab-initio’ training, but tail-wheel endorsements, type conversions, and aerobatic training. This too constitutes about 25% of my time. 3. I am the Chairman of a group of companies comprising a licensed telecommunications provider with a 155MB STM1 microwave backbone, seven small ISP’s specializing in secure networks for large corporate clients and the mining and TV industries, two data centers, and a producer of multimedia for museums and art galleries. This is the other 50% of my time. I should add that my expertise here is largely managerial, not technical, although I do have a reasonable ‘executive overview’ level of technical knowledge. Ok, that me, any more takers?
