My Litrefs Articles site is looked at over 100 times a day, but some of the articles are rarely read. It's just dawned on me that most of the unpopular pieces try to expose the tricks of the trade. At how many poetry workshops are poets told to muddy the water by throwing in some obscurity if a poem doesn't sound deep enough, or add loads of white space if a poem's too short or simple? If the poets decide not to use these devices, at least they'll be more able to identify their use when reading poems, so I think the articles are useful.
The situation where these devices are more likely to succeed is when there's no penalty for over-use. Unless more critics are prepared to say that they don't understand something, or that 8 words scattered across a page are unlikely to work, then these devices will continue to be popular.
