I signed off two hours ago and when I just logged on only three new questions have been asked. Is everyone at work?

Do you know what I find interesting on answerMug, Element?  According to my time, you asked this question at 6:49 am this morning.  It is now 2:42 pm my time.  I think it is cool we can see when a question was posted.  It took me a minute to figure this out, especially when answering questions from Didge and Ozgirl.
At any rate, I have seen that happen too!  For instance, when I came back on, there were 16 people on.  Within an hour, it has dropped to 7 and then will jump back up.  It just goes in fluctuation like that.  
It must look like I am always on because I leave my computer plugged in when I go to work, go to sleep, work in the garden, etc.  Many, many, and more many hours I appear to be here, I am not.
Wait!!!  That could be taken two different ways, hu?   Big smiles.  
Yes, Element, it does go in waves.  
I am glad you asked this question, though.  You normally have good questions.  If it appears that you are here, I sometimes come over and see what you've asked or what you have answered.  Like I did right now. :)  I find your topics and your style refreshing.  I'm about to leave to clean my car.  However, have a great night if I don't see you again this evening!  :) :)
