Parishioner and campus minister Christina O'Hara pointed me to Why Preachers Must Preach the Psalms « Come, O Thou Traveler Unknown
Our parish home groups took on the Psalms this year... one group already bailed and is reading something else. It has been a formidable challenge for them and the linked piece gives some good insight into why.
The early Christians quoted the Psalms often and found them loaded with prophecies of Christ. Some of their allegorical interpretations could be too much of a stretch, and so over time a more literal reading of Scripture returned. This was needed, but because the Psalms are poetry a literal reading is very difficult. Not to mention our "modern" obsession with analyzing "context" and such - talk about taking the romance out of an evening!
In Anglicanism, the Daily Offices follow the Benedictine model and make extensive use of the Psalms as God-given prayer. Sunday-only Christians are not accustomed to this, and so preaching is impoverished.
