There are a couple of sites that I check pretty frequently. They are AnalPhilosopher by Professor Keith Burgess-Jackson and Maverick Philosopher by Bill Vallicella. As their site titles suggest, they are both philosophers. They are also pretty interesting reads.
Incidentally, Professor Burgess-Jackson’s title refers to the fact that he is an analytic philosopher and anal-retentive. It’s not one of those philosophy/porn sites that are all the rage these days.
