I missed noting the anniversary the last couple of years, but as of the time this posts (10:11 UTC) it will have been exactly 7 years* since I started with my current employer. There have been ups and downs during those years, but for the most part it has been a good experience. It is hard to believe it has been that long though.
* I started at 17:30 UTC on Jan 11 2006, but since years are not an even number of days, the time of the anniversary shifts every year.
