Recommending a blog to someone is, for me, an easy question, because I only read two.
The first is VerseLogic, written by codepoetica (otherwise known as Alan Castonguay). The subjects he writes about are diverse, ranging from sharing a favorite poem to thoughts on new technological developments. Ironically enough, several posts happen to relate to new media – it was through VerseLogic that I first saw the “Machine is Us/ing Us” video, for instance.
The second is lainspotting, written by Lawmune (or Lawrence Eng). This blog was originally tied with his fansite for serial experiments lain (link to his site here), but has since branched off to discuss more general topics, though it still mostly centers around the study of online culture. Unfortunately, this one has not been updated in a long time now.
I feel like my recommendations are a bit lacking, since one is starting to look defunct, but these are the only two I’ve ever followed, except for maybe one other that isn’t even online anymore, and I’m very reluctant to try to recommend a blog that I’ve been reading for one day.
