Place your apps into folders according to what they generally serve you for.
I have FB, Whatsapp, Digg, G+ Twitter in folder named
Social.
Podcasts, iTunes, Shazam, Imdb app and BBC iPlacer under
Entertainment.
Maps, and Google Earth under
Travel.
Google Currents, Weather, Mobile RSS, Stocks and Wikipedia app under
News & Info.
All my game apps are under (not surprisingly)
Games.
I also have all unneeded by me apps like the YouTube app or Safari (I use Google Chrome) disabled under Settings > Restrictions or placed under folder named
Other on the second slide of my iPhone Home screen.
Hope I was able to provide some inspiration
