Le Livre d'Or

One condition would be that the groupblog would adopt your style. Similar to how the headfirst books have the same style but different writers. If you join the 37signals blog where you put up highly visual articles, in a see of more textual posts, you will still stand out.

It makes sense about not continuing with "business as usual" — I couldn't do it, either. But I can't see ghost writing as being satisfiying for someone with as strong a voice as yours. Being an evangelist for the likes of Apple or Adobe might be cool, but would that let you continue with the stream of consciousness riffs that have obviously been satifsying for you — and been so energizing for us, your readers? Don't know.

I think greater interaction among groups would result (mix up the tech bloggers and the marketers and the VCs and the usability people and, hell, even the sex bloggers) ;) and really spark some awesome conversations.

I think that you'd probably do well in a consulting role where you are helping companies who want to improve in the area of creating passionate users (products and websites). Your knowledge of the field is shown well by your blogging, and maybe getting out in front of people will give you more of a reason to stay passionate about this subject area (if not the blog itself).

Having said all of that, I wonder if Ande's idea isn't the best (regardless of what format you choose to go with for the blog). If it was still public with no comments, but you cross-posted entries in a private forum, you could allow people to respond and discuss in a controlled/private environment, but still keep the blog itself public. I'm not sure how much extra work that would be for you, but if it was negligible I would say that's the best option for running your site the way you have and seem to love, but keeping the riffraff at bay.
