As one of the FB commenters on the article mentions, the ironic thing is Monaco is one of the worst races to watch, from a pure driving point of view. Lots of narrow turns, very little passing, next to no straightaways (unlike Hockenheim where you can really let loose).
It depends on why you watch F1. If you want to see the drivers constantly on the edge, kissing barriers, and interesting strategies Monaco is unbeatable. If the rain hits it's usually spectacular. If you want to see cars go fast and overtake quite easily then thanks to DRS and KERS every other race is better. I like both aspects of racing but I find Monaco even more special now that overtaking is so common in other races (due to DRS).
Every spring I wish it rains in Monaco. There are few things more spectacular than an formula car racing the streets of Monte Carlo in full wet conditions.
To appreciate the Monaco track, drive it yourself in a video game such as Gran Turismo. There's tons of technical stuff going on around every corner, to find good lines for accelerating out of the turn. Elevation changes in particular create some very interesting and not necessarily intuitive characteristics on many of the bends. Monaco has a lot more curvy uphill and downhill segments than most Formula 1 tracks.
From the pure driving point of view Monaco GP is the most interesting due to its very low margin for error. Majority of drivers love this track. Racing sometimes is boring, but with current F1 upgrades like DRS, KERS and tyre degradation there is plenty of action on track.
