Starting sentences with "Hi" or "Hey", sentences like "Drop me an email", using unneccessary hyper words like "love", "excited", "we can't wait", "sneak peak".
Then this fake chuminess like "I'm nursing a hangover", "my cat typed this", "love to hear from you", smileys.
And then this self-deprecation: "it's really tough to know if we are on track", "our little app".
Guys, get this : this type of language no longer has the effect it had when it was used for the first time. This has become business speak - and real people don't talk that way.
I'm not a guy that likes referencing other people on this site, but take a look at the language that patio11 uses on his website. This is a normal way to talk to people.
Stop talking to people like they are a bit stupider than you, but to get to their level, you need to self-deprecate. It's not effective. That would be the gripe I have about your website. And apologies for being harsh, but my asthma is acting up.
