There appears to be a trend among some non-liturgical Protestants to follow the lectionary. A few years ago my extended family got together for a Sunday lunch and my parents and cousins were all talking about a great sermon they'd just heard on Mary and Martha and my wife and I laughed at how odd it was that their pastor had apparently randomly chosen the same Scripture as the lectionary. Then we started comparing notes and it turned out he'd been using the readings for some time (still is as far as I know).
I've stumbled across some of their denominational web sites from time to time since then and it looks like he's not alone. At the same time there are a lot of people who are absolutely furious about it. I bumped into a blog ranting against Nazarenes using the divine office because it was pure paganism (or something, good grief who knows).
The bad news is no lectionary. I found it wonderful to be challenged by readings I might never have preached on otherwise.
I also found the liturgical seasons really helpful. For example -- with the increasingly eschatological theme of the last weeks of Ordinary time, the climax of Christ the King, and then the chance to tie eschatology back to John the Baptist and Jesus ...
Ot try the segue from Epiphany with the theme of Christ as the revelation and the one revealing the Glory of God into the pinnacle of that revelation on Good Friday ... well, it was good for me, and maybe even for my poor auditors.
