What's the difference between the users page reputation score and the profile rep

Question

On the users page of this site I have a bold 17 beside my name. Against my name in the other pages I have a reputation of 96. What does the 17 mean?

Answer 1

17 is the rep you've gained this week, the default period. If you look at the top right, you can select a tab for week, month, quarter, year or all:

For example, Jon Skeet currently only has 2,470 on the weekly page despite the fact he's approaching half a million overall.

For week, you do indeed have 17:

If you select all, it gives you your overall rep of 96:

Answer 2

Every Stack Exchange Network site has a unique reputation score.
