This article isn't yet public on the main site, but I thought I'd release it here first. It's a really important topic that hasn't yet been discussed anywhere in this site's tutorials.
Tutorial: Compact vs Digital SLR Cameras
I think you'll also find that the tutorial takes on this topic from a different angle than you may have seen discussed elsewhere. It starts out by focusing on the three most common/important differences: the viewfinder, potential for different lenses and sensor size. It then discusses the implications of each for photography.
As usual, please let me know if you feel anything is unclear, if you notice any typos or just want to add something from your own experience.
