You are in Jonathan’s circles: "too" or "as well" or "also"?

I just read on Google+ that:

You are in Jonathan’s circles too

But I always thought that you couldn't use too there. Am I wrong? (because Google can't be wrong, right?)


Solution 1:

I think there might be a comma missing.

You are in Jonathan's circles, too.

Either way, this is the usage of "too" as a synonym for "as well" or "also".
