First, understand if San Diego operates by a traditional 6% model or something less. In Boston, 5% is standard. Next - it's always up to you to put the incentive up there or not, but understand that brokers spend a lot of time taking clients to view properties and understandably want to be paid for it. You can post no commission, but you may not get many (if any) agents taking people through your house, so you're reliant on the small pool of people doing a DIY route of finding homes and culling through redfin themselves. To me, the effort of marketing, needing to take people through the home (taking time off work), and even then dealing with people unwilling to buy FSBO wasn't worth the savings. We didn't have the marketing connections/channel or time off work, and knew we'd reach a smaller pool of buyers if doing FSBO. (We also had a negative experience going through a FSBO house ourselves. Don't have your kids at home during an open house if you do this.) If you can be unemotional, I'm sure you can figure out the right price for your house though w/o hand holding. And consider hiring someone to be there at the open house so you aren't there (it can make people uncomfortable).
I'd offer something, even if reduced (2%?) to the buyer's agent.
We bought a house without an agent, but sold with one, at a reduced fee that we negotiated in advance. We negotiated a 4.5% fee instead of the standard 5%, 4% if it was an internal client for another agent of theirs, and 3% if no agent. The buyer walked in with no agent, but got hooked up with the seller agent's company so we were in the 4% bucket. During the negotiations - we had 10 offers - the broker dropped their commission slightly (to around 3.3% is my recollection).
ETA: I'm an attorney (not in real estate), so I drafted the offer letter myself with some samples from friends. I could have paid a fee of about $75 and gotten myself licensed if I had wanted to, for when we bought the house.
