Just curious as to why you are of that opinion.
AJAX if implemented correctly is faster than doing a full page reload it also reduces the chance of you losing your post if there was an error.
It is also the first step in allowing me to detect if someone else has posted before you and to show you their post before you post, just in case you need to alter.
Gives a few benefits on this end

It won't be spammy AJAX like some systems where every 10 seconds it does a refresh of all the data on the page.
