I really don't understand this rant. Lobster is a title font, not a body font. Also unlike Comic Sans, it's actually pretty nice. The argument seems to be that Lobster is "overplayed" which is not only a snobbish, whiny thing to say but completely ignores the fact that Helvetica, Times New Roman, Arial, Georgia, etc. are used much more often. In fact you wouldn't notice Lobster at all except that it replaces the Arial you're used to seeing.
My point is largely that Lobster has a much more defined and recognizable look than classic "Sans" fonts like Arial and Helvetica and "Serif" fonts like Times and Georgia.
The look is recognizable enough that it evokes comparison to other sites, which you may want to consider. It can also break down the fourth wall between your site and it's viewers if they recognize the font. They go "oh, that's lobster, one of google's free fonts" instead of "nice logo" which, again might not be what you're after.
Professional designers can spot Gotham instantly, and will make fun of you for using it in a logotype. The relevance of that to a web app developer is zero.
