Very close, try:

<dtml-let channel="'slashdot'">
  <dtml-with "channels[channel]">
    etc...
  </dtml-with>
</dtml-let>

Everything in "" is Python, and since you wanted to make a variable
equal to the string `slashdot', you have to put single quotes around
that literal string.

It's a little more obvious if you consider that <dtml-with
"channels['slashdot']"> should work just fine on its own, though it
wouldn't be a solution to your problem.
