tweeps to follow, people to read... categorized

There are a lot of math teacher twitters and bloggers out there. What we've done to help you through the muck and the mire is make a few lists of bloggers/twitterers in some broad categories. To be clear, these are not comprehensive lists, nor are they meant to be. And naturally, there are definitely overlaps among the categories. There are tons more we could have added in each section. But we figured we'd give you a few to help you get started. If you're looking to simply search the online math teacher community for specific lessons, we have this #MTBoS search engine!

However if you're looking for a more comprehensive list, here's a searchable directory of people who blog and tweet!

By now you've learned how to add blogs to your blog reader, and how to follow various twitterers. So go at it!
