I was reading your views on blogs as personal and/or class tools and fully support the view that there must be hundreds of abandoned spaces out there! We do have to ask why bother!
I suspect in terms of blogs for learning, first of all the attributes of the tool itself need to be fit for purpose (eg your own use of the wikis and blogs for the webquest were your decisions. I have to say this is the first year that groups have defaulted to these collaborative tools rather than use the forum!). Yes, we're back to that word collaboration yet again:-)
Wikis clearly facilitate collaborative text construction in a way that blogs don't. The ease with which text is uploaded and reviewed is a definite attribute for creative projects, I feel. Maybe this is their strength and uses exploiting these features would seem to be logical. I do wonder if some wikis are more intuitive than others? I find myself reacting quite quickly to the 'look' of the tool and this can impact on my decision to make it a home for anything I do. You used different ones for your webquests - any thoughts on this, especially if that was your first encounter? I guess we could ask the same for most tools where we have choices, including blogs, but wikis seem to be a particular case in point:-)
Blogs clearly provide for discussion, but also seem to form a neat space for both sharing, archiving and display and I've seen various examples of them being used in this way. Along with the ability to tag entries, this seems to be again a specific set of attributes to act as a selling point.
This is a neat site that I explore with my UG class of primary school teaching assistants here in Manchester:-) In fact here are examples of blogs, podcasts, wikis all in one place - and in a primary learning context!
Sandaig Primary schoolWhat strikes me is there is no that much commenting and I felt this could be encouraged more (eg see the book review blog) but lots of 'display' - and clearly this can be seen by the children's parents too.
Here also is a nice example of Ning used in a global project around specific tasks that are aimed to make children more aware of others' voices around the world. Check thelink to the wiki from this main page for monthly tasks and uploaded projects
Voices of the WorldSee what you think - oriented towards younger learners of course.
