Probably going to get mixed opinions on this one.
Personally, I'm okay with it as long as it's not too obnoxious. And perhaps that's the rub, everyone's tolerance level for such things is going to be different. What may not be obnoxious to me, may very well be annoying as hell to someone else.
I say this because just last night, I saw a site with a single word...all the way across the screen...in 2 inch tall letters...SCREAMING at me to SING UP NOW!!! (yes, it really was spelled 'sing'...lol)
Right after I singed up...I DECLINED the site
If you decide to use it, definitely stay with your plan to keep it light and unobtrusive
