I learned this by experience….
You have an Orkut account and a gmail account….Which account will you open first?
Most probably gmail.
But I would open orkut first then only gmail.why?
Because logging into orkut automatically opens gmail.
So if you have logged into orkut,Just type in gmail on a new window,your gmail account opens up!
You have the following accounts to log in to,which one will you select
Option 1>Gmail opens gmail only
Option 2>orkut>Opens orkut and Gmail
Option 3>Google>Opens google,orkut,gmail, google page builder,notebook,…..so on..
So the best Option is Logging into Google account …
