I believe +1 buttons are here to stay. If you are already implementing share buttons then why not +1?
This is Google we are talking about and exactly how they are being used now remains something of a mystery. Rest assured the +1 role will change and expand in the future.
Even if the positives are hard to to see and seem to have little effect now, why not accept the small (if any) current gains and be prepared to reap the rewards of an early adopter?
