Stephen Fry is one of the most prolific celebrity users of Twitter
Stephen Fry has made online peace with another user of the micro-blogging site Twitter who called his posts "boring".
The actor and presenter, who has more than 900,000 followers, had threatened to leave the site, saying there was "too much aggression and unkindness".
But fans rallied round, attacking his critic and begging him to stay.
Fry and the user later apologised to each other, with the star saying his reaction had been "a mood thing" and he now felt "more sheepish than a sheep".
Fry is one of the most prolific celebrity "tweeters" and has supported the social networking site in interviews.
The disagreement began when the other tweeter said: "I admire and adore" Mr Fry, but added that he found his tweets "a bit... boring... (sorry Stephen)."
Fry then sent a message to the user, saying: "You've convinced me. I'm obviously not good enough. I retire from Twitter henceforward. Bye everyone."
He later said he was feeling "very low and depressed at the moment".
Almost immediately, the user began receiving angry messages from what he called a "baying mob" of tweeters.
Alan Davies, who stars with Fry in the television quiz QI, also waded in, calling the criticism of him "moronic".
The user later said there had been an "over-reaction" and he was "aghast at how far this has gone".
He also apologised to Fry, saying he greatly admired him.
The actor, who had been on a flight to Los Angeles, picked up on what had happened when he landed.
He wrote: "Arrived in LA feeling very foolish. Wasn't the fault of the fellow who called me "boring", BTW. A mood thing. Sunshine will help. So sorry.
"Feeling terrible for that poor guy. He had every right to call me boring. Not his fault it caught me at a vulnerable time. Pls be nice to him."
Comedian Alan Davies also became embroiled in the Twitter row
He then sent several messages directly to his critic, saying he was "so sorry to hear people have been abusing you" and calling the situation "awful".
The other user said he owed him no apologies, to which Fry replied, "Thank you for being so understanding."
Fry suffers from bipolar disorder, also known as manic depression, and has talked openly about his condition.
In 2006, he made a two-part BBC documentary called Stephen Fry: The Secret Life of the Manic Depressive, which investigated the reality of living with bipolar disorder.
