A Frog in the Valley

While there might be 5 Reasons Not to Use WordPress As a CMS I would still posit that using POGE as my guideline, wordpress would still be much more efficient than what most web design companies are pushing for… Read it again folks :

principle of good enough (sometimes abbreviated to POGE) is a rule for software and systems design. It favours quick-and-simple (but potentially extensible) designs over elaborate systems designed by committees. Once the quick-and-simple design is deployed, it can then evolve as needed, driven by user requirements.

This kind of design is not appropriate in systems where it is not possible to evolve the system over time, or where the full functionality is required from the start.

So if your company needs perfect, forget it. For all the others, think about it!
