I understand what you say but my feeling is that they will run together in tandem.

Example. I specialise in the range of rare metals. you will see that in my post to DB, re. Lithium, I posted several companies; there are possibly more; each of these companies might have a dozen or more sub sections, so there could very quickly be 100+ posts dealing with a specific metal in which few other members have any interest.

This number of posts would irritate even the most even minded, so in the necessity to sometimes disembowel a company, the Crow site is conducive to handling a different format, further, the relevent info will be on the same sub board thus facilitating one's concentration without interuption.
