I'm really curious what Alex's reaction is to the discussion here. He posted a link to the blog post, so he must be reading it, no?
The comments so far seem pretty negative, and not really for unimportant reasons.
The two main issues I see are: (1) too complicated as well as lacking contrast, so it will not print well on t-shirts, letterhead, and business cards and (2) the logo does not look like a shell without seeing the process that produced it (and in fact looks more like a pig, breast, or heart, all of which are kind of weird).
Were there business or other reasons for ignoring these aspects? Would it be possible to change the logo at this stage if this feedback were convincing?
