Elgg (open source SNS) wall-to-wall exchange with a work colleague. The domain is work but the informality in the exchange and its subject matter relate to the home domain. The literacy practice is asking for recommendations.
It's the early days of the Elgg installation so we're posting things as part of the process of getting to know how it works. The colleague whose wall I'm posting to is not a friend although we get on well and share similar interests. He's a good guy to talk to about techie things and is generous in his advice. There's none of the banter that's found in the txt message though because I don't know him so well and there's less shared history and discovered commonality.
