Just as any other popular social networking site or service, Google Buzz has began suggesting users new individuals to follow. The company made the announcement tonight in the official Google Buzz Team Feed. According to the team, suggestions will be made based on public connections on other networks, frequent email and/or chat contacts, and activity on Buzz.
Do take into account that only those individuals with public accounts will appear as suggestions. That means that if you do not want to be suggested to other, you better make your account private as soon as possible.
Once the suggestions appear, users can choose to either begin following them on the spot or ignore them. Ignoring a certain individual will automatically keep him/her from being suggested again.
