I don't really think it would be of any use for me. Why would anyone want to read:
Driving 120 miles to work
Working
Driving 120 miles home
Playing Ms. Pac-Man
Cooking Tofu
Eating Tofu
Playing Galaga
Watching a Movie
Getting up
Having a shower
...Start list over
Better yet, why would anyone feel like typing out that ---steaming pile of meadow muffin--- for all to see? Here is a sampling of the worthless stuff on my Facebook "What are you up to" newsfeed thing:
- makin' chocolate chip cookies!
- (name removed) feels like total death today.
- WTFs! Are people really complaining about the heat already? (This one is from a fellow KLOV and byoac'er)
- ARRRGGGHH! ! ! ME... HATE... WORK ! ! ! !
- Stuff I alway have on me, unless I'm in a hurry and forget (this line is followed by 5 pics of things EVERYONE has on them when out and about.

)
...this is with most people removed from what I can see.
Now there are a handful of people on there that use this function for good uses. This is why I don't turn it completely off.
I have no desire to 'twitter'.
