Some good numbers in there.

Surprised my mob are so far down.

So was I, but with Toulouse being low too (particularly relative to other Championship/League 1 clubs), I imagine the % of twitter users in France is much lower compared to the UK.

I suppose while some people may follow multiple super league clubs, Catalan are unlikely to be followed by British fans unless they speak French.

Leeds proving, once again, they are the biggest rugby league club we have.

Well, they should be really. Leeds' golden decade has run concurrently with the inception and growth of twitter. I do believe Leeds have the largest twitter following of any rugby club, in either code or hemisphere, which is pretty impressive & a decent asset to have to help generate revenues.

I'd imagine that Salford following is about 400 actual Salford fans with the remaining 27000 made up of opposition fans waiting on gobes next meltdown

Not strictly true. They are ahead of all the UK RU clubs I believe, which in itself is impressive, but they are well behind Toulon, Stade, Munster, Leinster and probably a few others.

Fair enough, admittedly I didn't go and check.

Amazingly, the OP presented figures for Twitter followers for each Club. Not their owners.

Please think before wiping your fingers over the keyboard next time.

With 36.1k followers, there's even more following the good doctor and awaiting his next meltdown!

Population of Castleford is about 40,000 - so 35,000 is a decent amount, all things considering

What is twitter
