That's how this should read. That would make unprofessional copy look like lazy professional copy, although I suppose there's a more general issue with tone throughout the post. Needless to say a lot of work still needs to be done.
As for the idea itself, I would probably try to appeal to qualities that nerds value. For example, they sure spend a great deal of time making sure their code is elegant. Maybe you could try to see how you can translate the rules of elegance as they apply to code into fashion parlance.
But what I took issue with was the tone you use in some of your writing. That sentence I quoted from your site just sounds horrible and my initial gut reaction to it is that you don't know the audience you're apparently targeting. The little secrets of fashion that will help me fool people into thinking I'm more awesome that I actually am? Yes, first impressions are important, people often judge a book by its cover, etc. etc. but ultimately, trying to keep up such charades (when not able to base things off some true aspect of who you really are) is unsatisfying, tiring and counter-productive. Ergo, I honestly hope that sentence doesn't convey what you really meant.
You say you understand our language, but I see little so far that confirms this. If I could give some subjective but hopfully constructive criticism: dial back the bravado just a little, show us some interesting research/data about your chosen topic, or just tell us an insightful story or two about fashion and nerds.
Using the word 'interwebs' and saying you liked The Social Network isn't - on its own - enough to convince me you understand my world. In relative isolation, it actually has the opposite effect to what I assume you intended, i.e. it comes off as 'try-hard' or contrived.
Also, my point in saying I like The Social Network, etc. meant nothing more than to explain why I've started 140 Stiches; I have a love for technology and fashion and want to give advice to guys in technology who are willing to take it.
OK. But you follow up the paragraph in question with 'Basically what I'm trying to say here is, I understand your language.' which implied to me that the purpose of the preceeding paragraph was largely to establish your 'geek credentials' in some manner. This (in isolation) is what rang hollow for me.
I hope that came out wrong, I really do.
The copy on this site comes off as pretentious and kind of annoying to me. Maybe it's just the groups I associate with, but am I the only one who thinks that the stereotype of the fashion-clueless nerd really isn't as pervasive in current reality as it once was?
