something 'shippish' or 'pixelish' into it wouldn't hurt, as just the letters sb may have quite a few meanings.
My thoughts exactly.
We're not "SB", we're Shipbucket and we shouldn't be afraid to put our name on the logo. The "SB" abbreviation is totally unjustified IMO.
Some pixel graphics elements would be nice as that is what Shipbucket is essentially.
If we are putting a ship in the logo it should be a profile, again to reflect the whole Shipbucket idea.
And just to throw another idea in the pot here's my take on it. It is "pixelish" and easily scalable down to 32x32 (not 16x16 though) and up. Also the color scheme can be changed to fit anything including black&white.
