Wrangling Parentheses
The most effective way to edit Clojure code is structurally with paredit.vim, but if you don't have time to learn that, Vim still brings a lot to the table for dealing with all the parentheses in Clojure code.

First, obviously, the % motion (:help %) is very useful. In normal mode, put the cursor on an opening or closing paren and you can:

Hit % to jump to the matching paren.
Hit d% to delete the parens and everything they contain.
Hit y% to "yank"/copy the parens and everything in them.
Hit c% to delete the parens and the text they contain and start editing.
Hit v% to select the parens and the text they contain visually.
