This is a bit too "ninety ninetish" for my taste. Looks like a button for a children games site. But paired with overall change, it's palatable.

Yeah I feel like the post button is actually moving back through the years in design. Something sleek, to something pointy, now it just looks like someone who's trying to build there own site found a new "customization" code to make there site "pop" and "stand out".
