Robbie and his channel must be loving all the free publicity he/they received this week!
Fair play to him, he found a gap in the market, grafted his arse off and now is making a business out of it.
The best thing is to monetise a hobbie or subject you love, will be the easiest piece of 'work' that you ever do.
People have been on Arsenal forums for 10 years plus and prob spent the same time and energy on Arsenal as Robbie has but unfortunately have nothing to show for it....
