You can communicate your ideas through websites or blogs, guest speaking, podcasts, video blogging, etc. You have to pick the one that works for you. I have tried video blogging, but a low resolution camera and not enough editing time resulted in a bad video that I would never send out to the web. I have participated in a podcast, but I felt as if I were rushing, and quite honestly, a bit nervous. Podcasts aren't my thing. I have successfully guest spoken, and find that I enjoy it a lot. My two biggest forms of communication for my writing ideas are guest speaking, and blogging. If you count Facebook and Twitter, than they can also be added on. Pick how you will communicate your ideas, and experiment with different ones until you find the one/s that suits you.
