Why didn't someone clue me into this.  My author bio for my first book “SAMS Teach Yourself Visual C++ .NET in 24 Hours” began: Mark Schmidt has been a software engineer at Hewlett Packard for the last 3 years.”

Now, if you go to SAMS website and look at my bio, it says the same thing.  It's been 2 years since I wrote that, so the 3 should be a 5.  Luckily I caught it in my 2nd book (”Microsoft Visual C# .NET 2003 Developer's Cookbook”) by just saying “Mark Schmidt is a software engineer at HP”.

So, Mark Schmidt's tip #1 for author bio's: Don't put a time based description if its for something that will change the next year and each year thereafter.
