I voted "to help on the forum" as I post mainly to answer other users questions.
but there are few more reasons too :
- See what's new on homebrew/hacking (My browser is open 24/24h on gbatemp, it's just a new click each time)
- Help developers (advices, debugging, etc.)
- help other users
- Find usefull softwares
- No particular reason (just check blogs and off topic forums, new answers, new topics)
- Search in the releases dats
