We launched http://justmigrate.com to help folks move from Posterous to Tumblr in few clicks (freemium). Our target were people who can't do much with their Posterous backup file and are stuck manually uploading their data into another blogging platform.<p>We shared the link on Hacker news on Saturday night and picked up some activity on Twitter, by Monday morning we got featured on TechCrunch. Phew a hockey stick, J curve or what ever you want to call it, it was beautiful, soon more websites covered us, our migration signup was designed to think less & do click click click, concluding with a tweet. All this gave us lot of love on twitter, thank you guys. However we were surprised by the payment conversions.<p>Hacker news - Highest & fastest conversion even though we were in front page for only few hours. Our expectation was very low from tech juggernauts as we thought they would be more comfortable moving to WP using the Posterous backup. They paid without thinking much, and this was amazing. Thank you guys, you are saving our startup.<p>TechCrunch - Surprisingly faired much lower than hackernews both in terms of conversion & inbound traffic, but they helped us spread across the internet through reblogs & tweets. Conversions took some time from TC users compared to HN. Tweets exploded from 5 tweets in 1min to 30+ per min. The whole conversion effect lasted only 3 days.<p>Engadget Spain - We got lot of inbound traffic from here but the real conversion spike happened next day, possibly they were evaluating our service. It was fun interacting with them on twitter in Spanish.<p>Life hacker - They covered us next day, conversions were slow to start with but towards the end of the week they helped us get more stable inbound traffic, ie above average facebook users. Also they score better on SEO.<p>Hope to get more insights from you all. Lot of users still don't know about Posterous announcement.
