I am still fairly new to Micro Niching, I have only about 10 sites currently. In the past I was under the influence that you wanted EMD.com, EMD.net, or EMD.org and if you cant get them, then you should just rule out that keyword and move on. Recently Ive been told that EMD+word is just as powerful as just EMD. I am getting ready to start another site and EMD.com is taken, only EMD.org is available. I cannot decide if I should go EMD+store.com or if I should go EMD.org. Hopefully someone has insite on this matter and can point me in the right direction!
