I've been in that same hypothetical blogevator numerous times meself. Only the other day, an online friend said: "how come you haven't written a book yet?" See, there's the thing. I would like to write a book, at some point. But, like you, I'm not sure my writing could hold up under the required attention span. I've thought of pulling some old favourite posts together into some kind of generally book-type item. Even consulted with a friendly literary agent at one point, to see if something like the Seven Deadly Agency Types series might be worth stretching out into a book. In the end, though, I came back to my original original thought. That is, if I'm going to write a book, it's going to be something original. I can't get comfortable with reheating my assorted leftovers. My areas of attention tend to leap around so much, any such effort would inevitably be the literary equivalent of bubble-and-squeak. Yummily satisfying for the hungover, perhaps, but an object of disgust to many. Sorry - this doesn't really answer your question. If our hypothetical anonymous blogger in a lift was asking which of his/her posts would be most suitable for re-purposing in book form, I'd be inclined to side with Dan's advice. Just supposing our suppositional blogger had at some point written a long and excellent post on the relative advantages of polymathy over specialization, I'd venture to suggest that single post alone might hold the seed for an entire book. Someone needs to write the definitive 21st Century work on the idea of "Renaissance Man (or Woman) 2.0". Or take Van Vogt's idea of Nexialism and explore that fully. There's a book I'd buy. Screw it - there's a book I'd even love to write. Ah, looks like I just gave the idea away though. Oh well... Tee hee - just noticed the captcha for this comment is "s7uw5". Coincidence? I thinkee not.
