"of course" vs. "off course"

I was reading an online newspaper this morning when I came across an error which could easily pass as a non-error:

• And off course i follow one of the guys who created this micro blogging Jack Dorsey.

In the sentence above, the phrase “off course” is wrong.

• of course – without any doubt, certainly
• off course – away from the intended direction

Examples:

1. “Of course (certainly) you can go out and play,” mom told us.
2. The concert begins at eight but you can’t enter without a ticket, of course.
3. Due to the stormy weather, the plane went off course and crashed into the ocean.
4. He was a young, bright student, but he went off course and joined a triad later in his early twenties.

Businessmen succeed because they’re persistent, and of course, once they become greedy, they will probably go off course and get themselves into trouble.
