Back by popular demand (OK, a couple of people asked what had happened to it) is our semi-regular look at what rugby's leading names are saying on the social networking phenomenon that is Twitter.

There appears to be no stopping the growth of the micro-blogging site and it continues to hit the headlines following Wales' decision to impose a Twitter ban during this year's Six Nations. Thankfully there is still plenty of banter going on out there but sadly it crosses the line on occasion.

Former England hooker and BBC commentator Brian Moore pulled the plug on his account (@brianmoorerugby) this week having had enough personal abuse aimed his way in the wake of the Six Nations opener in Cardiff. Love or loathe his style of delivery, his Tweets were often insightful and his concise analysis will be missed.

He's not the only one threatening to down tools in the face of some out-of-hand banter with former England star and ESPN analyst Austin Healey - never one to shy away from a verbal exchange - pondering his next move going by his latest post.

"@brianmoorerugby I think I'm going to just go back to abusing people in person has a much better feel don't you think"
