Tendulkar was bitten by the Twitter bug early this month, while Amitabh joined Twitter Tuesday and got plenty of welcome messages from various celebrities.
But the 67-year-old, who regularly writes on his blog and also has a mobile blog and a voice blog, is excited with his first day's experience on Twitter.
"Day 1 on Twitter, Day 757 on blog, Day 138 from the year... endless days of love and affection to those that count and follow... love, " Amitabh posted on his Twitter account.
"33, 341 followers in a few hours of starting! Tweety baby I love you!! Keep it rolling, " he added.
Currently the actor is following his son, Abhishek and Sachin on the site.
