Lokamanya BaL Gangadhar TiLak (Pls pronounce T from TATA and not from tisra kaun) started this festival to unify Hindusthani's against Britishers. This was the first time when "ShriGanesh Utsav" went public but it was already being celebrated in the houses of Maharashtra which is called as "Gauri-GaNapati" festival. Now a days all festivals have become center of enjoyment and the main aim has been lost. People having lots of money can celebrte daily while those striving can not even think of it. As Mr.Narayan Murthy righly said, present generation does not have any idols or mentors like Lokamanya TiLak. It is just fun/enjoyment and materialistic life. So have fun but don't forget the aim of Lokamanya.
