Very nice concept - I think this could work really well. Love the white-on-black version, but not convinced it would work in site navigation. I think the geek portion of the logo is spot on, but that the salt portion could use some work. I don't think that the grains of salt work as well as they might. Perhaps the entire word could suggest salt pouring out (somehow) rather than the individual dots? Would like to see some colour variations too. Thanks for your submission!
I don't like how you changed the salt shaker in example: #60 and example: #61 - the concept works much better when it's suggested by the negative space, although the colouration of example: #61 (suggesting salt inside the shaker) could work - I wonder if that concept count be used to suggest a pile of salt in the word salt? The versions with outlines are also quite nice. Still not sure about the texturing on the word salt, though. I think the logo works better with solid colour, but I realise that the salt needs to be shown somehow to make the design work.
