I started with Python and still miss its lazy generators. K's grain favours calculations that drive down long 'straights' of arrays without many conditional turns, but it's eager-first, which can be a drag for some problems (eg making a prime number generator object that I can take an arbitrary number of elements from lazily). Still, it hasn't been as bad as I feared.
I like the choices of primitives in K and the novel ways they can be combined to do things more efficiently (and with fewer pieces!) than you may expect. Good examples are 'where' (&), the grade twins (< and >), scan (\), and eachprior (':).
I love the adverb syntax: each (') lets you map a function over a data structure with zero syntactic effort, and 'over' (/) and 'scan' (\) make reductions trivial.
With regards to an on-ramp, I started with John Earnest's oK REPL and did a bunch of Project Euler and Advent of Code problems. I then moved to trying to understand the examples on kparc.com. I then converted a spreadsheet application from JS to k7. In all of this, John's documentation was essential.
For me, having single variable names isn't paramount, but in some cases - particularly functions - I can see it helps to 'drive' your mind towards finding simpler ways to do things. It lets the characters that do the 'real' work come to the forefront.
