So, in addition to looking at the list to click through at Lenandlar's blog, you can also subscribe to the combination RSS feed if you use a feed reader: Rhizo15 RSS combo feed.
Alternatively, you can access the OPML file for that combo feed here: OPML file. You can also look at HTML scrolling view, 20 posts per page, here: Rhizo15 posts: scrolling. (Those are more-or-less in date-based order, but when I add a new blog, it grabs all the posts in that blog and puts them at top, with new posts at that blog then going into the standard newest-first date-based display.)
For Inoreaders out there, I made an Inoreader bundle: Rhizo15 Bundle. Anyone can view the bundle, which is a new way in fact to preview how Inoreader works as a feed reader... basically: it's Feedly on steroids! mega-steroids!
Admittedly, there continue to be a few blogs I cannot add to the combo RSS feed:
(apparently not using a label for Rhizo15 posts?)
(also apparently not using a tag or category?)
(Lee told me IHE uses Drupal for the blogs...?)
(I can't see how to get a tag-specific RSS feed here)
So, if anybody has insight into Drupal or Github, let me know! I've had fun learning for myself about how tag-specific feeds work not just at Blogger and WordPress (which I knew about already), but also at Known, Tumblr, and Weebly.
Anyway, I wanted to provide this update about the combination RSS feed... and now I am going to go do some reading and try to get back into the rhizo swing of things after having been out of town and (mostly) offline last week. :-)
