It seems the exclamation point is ubiquitous in porn writing. Free sites, galleries, hubs, link lists, TGPs, blogs, site tours, newsletters--they're all filled with exclamation points which have no real reason to be there.
I'd love to see the test data which everyone seems to rely on. You know, the test results that say if someone uses a lot of exclamation points in their writing, including multiple exclamation points, the reader will get more excited and therefore will be more likely to click a link and buy a membership.
I wish sponsors had an "exclamation points/no exclamation points" option in their promo tools section so I could opt-out of having them appear in all the wrong places.
(didn't I say some of this already?)
--and to get back on topic...
I usually figure about 30 minutes total for each post, including collecting whatever is required for that post, no matter when I collect the information/pics/links/etc.
Rewriting sponsor feeds can cut that time in half if the photo is usable and the links go to the right places already.
