Just one to start with...
gabion
has many interesting articles...last few months were not his best...but the article section has a lot to read...

agglutinations.com
hughpearman.com (mostly brit, but interesting)
archpaper.com
bdonline.co.uk (brit again, requires sign-in)
archis.org (interesting, but a pain-in-the-butt interface)
loudpapermag.com
a-matter.com
americancity.org
core77.com (more culture than arch)

maybe i've gotten lazy, but the editors here at archinect are pretty good at picking some of the most interesting stuff of the day from a bunch of places that i haven't found yet. just watch archinect news.

besides our own stuff (*ahem*), some sites you may want to bite into are
www.designobserver.com
www.designboom.com
www.agglutinations.com

just to name a few

and some recently added links, if you are a particularly brave and patient reader:
www.desphilosophy.com
www.brookings.edu/urban/

just the tip of the iceberg

is another

is also another source for other links, but it's in no particular order

thank you all - I am reading through archinect news (maybe not daily, but almost...), but wanted to download a few longer articles occasionaly - I will check them all now!

these are other.
arcspace.com
archnet.org (more islamic)
archiseek.com (more about competitions)
