It is just right. To be considered a fully fledge-fledged member of the site, gaining 50 rep is easy in a single day.
The bounty system is to get attention for questions that are difficult to answer, not an express support queue. A question can only receive a bounty after 2 days anyway, more thenthan ample time to get 50 reputation.
I honestly think 90% of users that set bounties are misusing the system due to lack of understanding. YourYou're paying for advertising your question, not express support.
Also, it's easy to get 25 reputation on a single answer. Just accept it and up vote-vote it, and you have given someone 25 reputation pointpoints. With that in mind, what would my motivation be to answer a question when I don't get any more for my effort then I can normally?
