Looking for game design/programming/news blogs/sites-with-feeds which would be interesting to all others here. Currently experimenting with adding kind of a dynamic blog feed to the site…

http://www.idevgames.com/blogs (This is not permanent)

So anything game dev related, post a link for it.

http://www.pixelprospector.com/ and http://www.pixelprospector.com/indev/ are a couple of my favorites.

Rock, Paper, Shotgun - PC-only games news blog, lots of coverage of indie games. Great writing. Through them I recently discovered Kill Screen. These are not dev-related, exactly, but very good criticism.

http://www.71squared.com/ iOS Game Development blog (from the authors of Learning iOS Game Development).

FYI, this can include your own game dev blog.

Once I start posting again (going to restart some projects this summer) then I'll let you know. Meanwhile it's pretty useless

My blog:

Not sure if it's 'exactly' what you're looking for, but 90% of the stuff I write in there is game related in some way or another.

For news on the Game Maker world (which involves the Mac, of course),

http://www.gamemakerblog.com

And, has anyone listed TIGsource?

tigsource.com

And, eventually Vetra Games ought to feature news on our main site soon... everything's in a limbo but we're trying to correct that:
