Your "About" section is more clear than the descriptions on your homepage. Perhaps you can find a better way to convey your value proposition. Your homepage doesn't tell the average user what you do very clearly. Below are some small copy issues.
"Ride, Rent, and experience a new way to travel." -Either capitalize the word "experience" or lower-case the word "rent". Right now it's not consistent in punctuation, in my opinion.
"With Outpost you can check out many person to person services into one spot!" -change "into" to "in".
"Pick a ride share to get to your destination or just walk there." -You need a better way to convey the value of your site in these small descriptions on the homepage.
