The fees should go down. They are actually adjusted by the witnesses. Each witness votes for two fees. There's an operation fee and a bandwidth fee. The operation fee is a flat fee that gets charged for every operation. The bandwidth fee gets charged depending on the amount of data contained in an operation, so a huge post costs more than a short post.
You can check this page and see what each witness has set for fees.

The resulting fee is the median of all the fees set by the witnesses.
I noticed today that a vote costs 0.002 Blurt. It was a lot more than that a few days ago when the fees first came out.
With there being a fee for every transaction, and I am just guessing that claiming rewards in the wallet is a transaction, just like powering up or down, that pretty much means no curation rewards for the small accounts. Pretty much no net reward for voting. The only accounts that seem to be benefiting from voting/curating are the larger accounts.
That being said, I am still here, still evaluating the cost effectiveness. Maybe I should join the dobartim crowd at least they are making 6.00 + on most of their post. (not gonna happen)
