Clearly this is a very controversial topic, but the general attitude for most of the supporters (myself included) appears to be that if no serious negative effects have been exposed from consuming Soylent in three months, it must be safe to try.
Is there any possibility that consuming Soylent for a while (say, a week to a month) and then stopping cold-turkey could be significantly harmful to one's digestion? Maybe? I guess we'll find out when the first round of supplies is consumed.
Another thing, props on the campaign and having already been funded, but let's hope the next promo video does less to seem like a run-of-the-mill infomercial... :\
