Independent of the elegant typesetting it produces, TeX contains well-designed notation for mathematics, reflecting the algorithmic bent of its author, Don Knuth.

Mathematics doesn't change as frequently as desktop publishing, so it's a good bet that the TeX (e.g. $\int_0^1 \tau \, d\tau$) is going to be around as long as people talk math online.

That said, I think there are much easier-to-use and less error-prone desktop publishing tools (e.g. Scribus) for less math-heavy domains, like magazine layout.

Anything graphics + text heavy I switch to Scribus. The closer what I am working on can be described as a brochure the more likely I will use Scribus.

TeX, for me, tends to be articles, reports, and documents that I expect to use the same format again and again (or the format is provided, such as from IEEE).

yeah, definitely. i've switched to lout for non-mathematics-heavy stuff myself.
