Update:
I got it to work. There was some kind of conflict with one of my other non-activated plugins. I had adhesive in there along with two older image browser plugins (not needed in 2.5) that were non-activated. Once removed, wp-sticky now works fine.
Very nice.
Update II: Unfortunately I can only get multiple stickies to work over multiple days if I edit the date or choose “announcement”. If I want two stickies at the top that were made on different days(and to have them stay there), I need to edit them to the latest day or set hem as “announcement”.
Adhesive was def a notch up on this.
