For me, it's convenience, precision, and readability (no need for all 
those ampersands and quote marks.) I use it mostly for reports, 
auto-generated emails from my server, and sometimes dynamic HTML 
construction. It also eliminates the need for multiple "replace" commands.

For example, imagine a text template in a custom property named "cText":

Dear [[username]],
   Thank you for your interest in [[productname]]. [[productname]] is 
available for download at [[productURL]].

And the script:

put "John Doe" into username
put "Zygodact" into productname
put "http://mydomain.com//zygodact.html" into productURL
put merge(the cText of me) into tResponse
