people are going to suggest for you the things they like, not necessarily the things you will like. for example, when i travel i make use of Clirc on the ds, i highly recommend it, but it is only going to be interesting to you if you chat on IRC. here is another example, nitrotracker is a solid application for making music, but i don't use it so i would probably not remember to recommend it.
it might be easier if you simply told us what type of things you are looking for. do you want chatting applications, art applications, music applications, multimedia applications, etc? do you want rpgs, platformers, or adventure games? do you want emulators and interpreters?
another suggestion is simply to go through the files on filetrip and see what interests you. in the long run it may save you time as you won't be clicking on every suggested link or collection of suggested files.

homebrew can be very personal. find what you love and start to build your own list of suggested files.
