semantic markup - Current usefulness of semantically correct HTML -

-

i'm working on new website, , i'm trying decide how want balance need semantic correctness, other important stuff, development time. know semantics supposed important seo, , accessibility blind people. , important me, , shouldn't take time. i'll design them in, beginning. anyway, question is, else semantic correctness currently useful for? if there's else may consider worthwhile, i'd rather spend little time build in, wait until later, when may more difficult.

also, know there lot of future possibilities. good, , not (i've seen terminator movies:). i'll wait , see happens those.

edit: should have mentioned supporting old browsers important project, being semantically correct won't easy. since haven't done lot of browser programming.

i did more research, can answer own question.

other making sure site accessible disabled people , search engines, there isn't important semantic correctness, project. , think search engines , screen readers sophisticated enough these days, handle incorrect semantics, long content structure isn't confusing.

i can see semantic html elements being useful documentation though, long doesn't complicate code.
