A few things!
Sharon Salzberg has some thoughts about anxiety. If you use Facebook, check out the BCIMS page ! I post articles, pictures, and quotes there regularly (usually more than once a day but it varies a lot!). Topics are generally meditation related, with a slant towards social justice but covering the range from news about Therevadan monastics to everyday life practice. Most of the teachings are from Therevadan/Insight sources but I do post stuff from other traditions, especially popular teachers like Thich Nhat Hanh and Pema Chodron.
