I've had "GREAT" and "HORRIBLE" experience with SodaHead. It was once a "conservative leaning" site but since more than 50% of the site was sold out to a group of "left-leaning" owners, they have contracted 26 and 27 year old Californian females as "full-time" moderators. I have received a personal email on that site from a person who bragged about her relationship with one of these moderators. When I defended a fellow Soda Head member from attacks from a liberal female member, both of us were deactivated. The liberal lady for one day, myself, permanently!
While I was a member, I wrote no fewer than 225 blogs for open discussion. I NEVER posted any blog that did not allow all factions a choice of answers and the allowance of debating those answers.
However, I could not fight the friendship relationship of the NEW very, very LIBERAL moderators who consistently side with their friends. IF anyone remembers the Yahoo Buzz, they had "one-sided" moderators as well who deactivated ONLY the conservative members. I fear that Soda Head will soon join The Buzz as soon as their paying Sponsors find out the truly only have but a few hundred active members rather than the "millions" they declare. For as many of individuals, like me, who have been "canned," we STILL count as members to their advertising accounts.
