Ask HN: Review my startup theBcard - make and share free online businesscard

http://www.thebcard.com/ I am interested for your criticism and UX. Why are you not using the site? What made you leave the site? What could be improved? etc. web site has been established a year ago, has been seen a small incremental growth but is not even close to the tipping point. thank you in advance, Kaspar Korjus www.theBcard.com/kk87
