And AddOn E:

Keeping up-to-date can be quite tricky, and not just on the programming end.
Learn about the AddOns you use. Read their changelog, read their bug reports, understand what each new version brings.
Sometimes incompatibilities arise. AddOn A has been updated, but AddOn B that relies on AddOn A hasn't been updated to be compatible with it's newest version. Or an AddOn has had a change to it's settings which require a certain procedure on the user's part to get the AddOn fully functional again. Or perhaps a recent change has made one AddOn incompatible with another you have installed. The list goes on.
Add to this the situation where version numbers are different across all addons, across different sites, and auto-updaters can and do get things messed up at times.
Keeping 100% up-to-date, 100% of the time isn't really necessary. Use these programs wisely.
