Boston Globe technology columnist +Hiawatha Bray
also sees Google+ as a Next-Gen Twitter:
"Google+ works much like Twitter. You don’t have to friend people. Just add them to a circle and follow their message postings. Already, I have dozens of strangers following my messages. I can block them if I choose or add them to a circle and begin following them.
Forget Twitter’s notorious 140-character limit on message length. Google+ lets your posts go long. You can include videos, photos, or audio files, just as you would in a Facebook posting."
