the example (link) gives:
E107: Missing parentheses: <SNR>17_StartZekyll
(For exact copy of the example, it is: E107: Missing parentheses: <SNR>16_AppFunction Below is my stripped, faithful version, I've removed comments and the multi-dot parts ("... whatever ...") and modified the first key binding.)
What can be wrong?

The mapping given as an example misses some parentheses for the call command. You have to correct
map ... call <SID>StartZekyll<CR> ...
with:
map ... call <SID>StartZekyll()<CR> ...
in both mappings you defined.
