I was on Sodahead for six years, thus almost from its inception forward. Although I would say that most of their members lean conservative, especially when it came to acknowledging Barack Obama, the format, concept, and tools that SH put at your disposal certainly made a difference and gave me a fun, valuable means to express, entertain, and educate. In fact, a recognize a fellow Sodaheader in this thread "Rebel" who posted a comment to my most recent SH post. I probably may have to agree that there isn't much on the web beyond SH when it comes to writing opinons and enjoying responses and feedback.
