The forums are almost self-maintained. They were surprisingly easy to set up. I don't feel any pressure at all to participate here.
I have still no idea where the time I spent on writing the book came from. It took about two years, and I know that it at one point reached almost 150,000 words before I cut out chapters to grind it down to 100,000 or so. I can finger-type at about 70WPM, but my usual typing speed for blog writing is probably more like 40 WPM when I need to go back and change a word or two, etc.
This means that it has taken at least 2500 hours to write the book and probably more like 4000. Thinking back, I can't for the life of me figure out how that happened. I guess it's just the sum total of a few hours here and there over a long time.
I'm having a hard time getting started on book#2 though. I think book#1 is still too close---I still have too much going on WRT to that one.
I don't know how much time Zev has spent on editing, but it took me about 50 hours just to transfer his corrections back into the manuscript!
The blog is definitely the hardest one to write. This is mainly because of the time-pressure to post regularly and the need to remain interesting. The latter requires lots of reading to fuel the thinking. It's quite apparent to me, having a record of my thoughts, how stable my thinking is on various subjects.
The OPP plugin was a huge relief. Still, however, it takes a long time to develop a theory to maturity. One should probably figure on 1-2 years of contemplation. I think the ERE theory has been exhausted by the book project---it's canonical.
I'm still contemplating "a theory of investment" since I like to solidify my understanding here as well instead of just relying on incohesive intuitive notions.
I am likely quite handicapped by not being willing to repeat myself knowingly.
