I believe that Dave Pollard's illustration in the first-cited entry is quite accessible and reasonable, and, at the same time, it is also an exhaustive listing of the steps taken in "serious" [one form of serious, anyway] weblogging. Kudos!
In what remains of this entry I will make some initial observations about the process he describes in his metablogging entry.
First point (derived from my interest in knowledge-making, learning, etc): Perhaps some of these steps could be better [i.e, more effective blogger action would derive from the step] stated in the fuller context of learning and translating(blog writer doesn't yet know but will first find out and then figure out how to explain] or simply translating present tacit knowledge (blog writer will figure out how to explain what s/he already knows). Example: the steps involved in the Research/reading section of Pollard's flow diagram are aptly stated in terms of what have come to be familiar blogger actions. However, if the issue really is expanding individual and collective knowledge, then the inter-blogger steps are a "surface" process which is an overlay on another, less accessible phenomenon, namely,a group's acquisition of new (at least to its members) and relevant knowledge. IMHO the explanation of the blogging process in this context would be better served if some explanation of essential knowledge-making actions were folded into. or at least linked to from within, the discussion of sequential blogging behavior.
Second point: Lest it somehow slip your attention: Dave's breakdown of the time spent on the four major actions involved in weblogging should make clear the level of commitment involved in writing serious weblog entries. (If you do the math you will see that by taking on weblogging he commits himself to over 18 hours per week. )
By the time you have read this, or soon after, I will also have written ** and posted a story in which I examine the 43 steps of his blogging flow diagram. This will be as the steps relate to knowledge-making within this same community. In order to do this so that reader and writer alike understand what's being discussed I'll also have listed some specifications of this learning community.
*11/10: missing link to my entry on first edition now replaced; link's absence caused by mistyping html code. For the average to subaverage coder, moi, there is a coding/recoding element of time consumed in blogosphere participation that is not accounted for in Dave's 18+ hours per week. **11/11: Promises, Promises! Have worked on it and am continuing, but naturally, at least for this multitasker, it is going more slowly than anticipated. (11/13). Making considerable progress but have lost all hope that there is anything other than a general outline of blogging that fits every effort. I see no future for a detailed "one size fits all" flow for weblogging. Process will vary considerably, to say the least, with intent, and --- that's as it should be.
