I'm having a problem with the Facebook App! I don't use it a lot so I don't like to have alerts for it every two seconds (like when 100 people comment on something that I commented on). I made notifications for Facebook inactive and have tried everything I can think of to turn it off.
I'm sure there is a very easy solution for this, but right now all I have done is logout of it when I'm not using it... but I like to have it logged in because of the contact sync. All I want is to have alerts turned off.
If you have an HTC device, go Menu -> Settings -> Accounts & Sync. You will see that there is a "Facebook for HTC Sense" entry. Edit that entry so that it only syncs your contacts/address book. At least, that's what I had to do.
