I especially like Stephen's summary, reproduced entirely here:
In this article, [author] presents an [article type] on [technology type]. The point of the article is [conclusion]. This is similar to something I said in [previous article], which of course [is now|is not] mainstream. [Edublogger] once also said [comment], but was [wrong|deluded]. In my opinion, [author] is right when [he|she] says [something I said], but misses the point when [he|she] says [something I never thought of].
Since I started my research in creating learning technical systems, I have realised that there are at least three communities involved in this process, listed below in reverse order of importance .
1. Technologist which produces technical platform in which learning may occur. Examples include web servers, discussion forum, blogging software, Fablusi online role play simulation platform, etc.
2. Educator/Learning facilitator who uses the technical platform to deliver the learning. This includes customising the content of the platform (e.g. using blogging software in the learning process, creating/putting subject matter specific content into the platform,...)
3. Learner who uses the technical platform to learn.
The lowest level is "reading" material created by  in . (Think first generation web: lecture notes on the web in which web is , the lecture notes is by  and  reads.) We have since moved from this model. For example,  may identify a specific  implementation and ask  to use  to post learning episodes.
Note: "ask  to use " is somewhat an action of .
