Ask HN: Review my startup – itripd.com

Hi HN, http://itripd.com is a travel startup where you can "share your travel adventures and discover others". Looking for any constructive (or destructive) criticism people may have to offer. Initial target audience is travel bloggers. itripd is intended to be used by travel bloggers in a similar way they already use facebook, pinterest and twitter (to show case their trips) and will act as another channel of traffic to their own web site.
