Use of discussion boards seems to be on the increase again and I wonder if this is a sort of backlash against the relative complexity and time commitment of using communications tools based on blogging functionality. As a great fan of social networking and systems like Elgg and Ning, I have spent the last few years encouraging colleagues to use these in preference to the old fashioned, heavily structures, largely text based threaded message forums. But, for some things, I have found discussion boards in our VLE and Student Portal, the Forums here in Eduspaces (once upon a time) and those available in Ning groups more effective and significantly easier to use. I am gradually forming a better idea of what systems like Elgg are good for and what is better suited to focused threaded discussion. I hope to turn this into some sort of guidelines/best practice document, probably collaboratively written in a Google doc in due course. I would be grateful for any thoughts on this and any observations on your own experience, dear Reader, of the two different systems.
