Look my sims is a blogger too!
The tasks is to create a blog post, after which you will be awarded with simoleons, XP and other items for future use.
There are different items that can be used for skill building like computer for writing, paint easel for art, microwave for cooking and guitar for music. Later on there will be more items available as you increase levels.
You also have to take care of your sims, the green buttons in the middle indicates your sims needs. It also needs to sleep, pee, bath, eat, be entertained and socialized. The first five can be done by clicking button itself or the item to be used like ref for food. To socialize you need your FB friends to be neighbors, a daily visit will give you free energy and social points.
I am totally into sims (again) and might do a follow up post, upon request? anyone?
