I agree with Chris Li that it is mainly new information that fuels online community discussion, and add that it motivates people to meet up for more community and discussion.
Quickly again, as I need to get back to work -- I agree with you and Chris as well, that new information is important to have in a discussion forum.
That said -- no, I don't think there is any kind of blame being placed towards the internal training discussions due to
a dearth of other topics to talk about; I think there are other dynamics at play which make it difficult to continue a fruitful discussion (which, again, I will address in the near future).
I, too, know that there are many folks out there who are researching, exploring, and experiencing much within the aikido world, and I would very much like to support their inclusion and acceptance here on AikiWeb.
