BUD Chart, page-1832

Even more basic than that - SIS got 1847 views on their most populated thread - BUD has nearly 700,000 views on the BUD Chart thread

Advertising is all about eyeballs and contextual relevance - put you ad where the right people are looking

So SIS is very shrewd to place an ad on the BUD thread - BUD always had the opportunity to put its own ad on its thread - and block out others - but chose not to do so

And of course BUD can go place an ad anywhere on HC too - them's the rules - so wise to use them to your advantage
