Xeetter is showing you on a Twitter search page, timeline, or list whether a person is also in XeeMe.
If the person is in XeeMe
It shows a blue sphere
Clicking on the blue sphere opens the person’s XeeMe
If the person has no public XeeMe, you may need to be logged in XeeMe to see it.
If the person is not in XeeMe
It shows a grey sphere
Clicking on the grey sphere allows you to add the person to your social contacts in XeeMe. You need to have an active cookie from your XeeMe account to add it.
