Address reuse leads to a reduction in privacy for everyone,
If OP is planning to post his address on a website, he obviously doesn't care that the address is being associated with his website.
Just as you have your address posted on your profile.
If you (as a sender; e.g. as donator) care about your privacy, you should not rely on the receiver. That would be a huge mistake.
If you care about your privacy, make sure that you send mixed coins. But don't rely on the receiver to always generate a new address for everyone.
and incremental reduction in security
Calling address reuse a reduction in security is exaggerated.
Ideally, the OP should generate a new address each time he receives a transaction
In OP's case this might not be necessary. So there is literally no good reason for him to invest time and work into something he might not need at all.
If i understood him correctly, a single static address is absolutely fine for him.
