If an artwork never gets any attention from anybody, then obviously it's got problems. If it gains attention from a very small elite, then it's presumably doing something. Finnegans Wake gets a lot of attention from certain people who become passionate about it, who are usually very good readers in general. Although - I often talk about costs and benefits - it seems to me the costs of reading Finnegans Wake are not worth the benefits, however many there may be. And it's the same with the more arcane among poets, Zukofsky and so on.
