What's in a name?

Further to my post last December about how if you take into accounts all of the different spellings of the name Mohammed, that name was the second most popular name of 2007 for boys. Today I learn from The Independent (it was a quiet morning and that was the only paper available at this client) that

"while many traditional names are fading into obscurity, other recent additions are flourishing. Mohammad was the 17th most popular boy's name last year, while Muhammad was the 38th most popular. More boys born in Britain last year were named after the Prophet than were given any other name."

I am not sure if I was right in December or The Independent is right now, but should we be coincerned that the most popular boys name in the UK is a variant of Mohammed?
