I thought I posted this in March, but whilst searching the archives I couldn’t find it, so here it is… UIWeb have collated a useful list containing the best of CHI-Web & sigIA-l discussions.
It is a quite useful summary and the discussions are extremely interesting, particularly if you have an interest in the area of usability and HCI.
The CHI-Web and sig-IA mailing lists are two email based discussion groups on the topics of web usability, design and human computer interaction.
