I suppose this might have some utility to some, but you are trusting a hacked over a weekend site with your Linkedin password?<p>The trend to give out passwords to 3rd party sites needs to stop, because security risks eventually become too great.
Built an app with the same name last year, also running on Sinatra: <a href="http://linkedout.jupo.org/" rel="nofollow">http://linkedout.jupo.org/</a><p>Very different purpose though. The original (snark) LinkedOut app lets you export profiles as clean PDF resumes.
Not bad.<p>Since LinkedIn is 90% recruiters this is what I'd really like to see from an app: Fill in a few of your skills and it autogenerates a profile with keywords that recruiters search for.
Accepting every connection on LinkedIn pretty much defeats the purpose. I only add people that I could ask for personal introductions to others ensuring my LinkedIn network is actually useful.<p>I suppose if you've never gone through the backdoor in order to meet someone, LinkedIn could seem like a big waste of time. For me though, the network graphs of who I know that I can ask for an introduction are quite valuable.
In addition to concerns raised by other posters, bonus points for the invalid SSL cert. This site must be a honeypot to name and shame the criminally stupid. Eventually the official raison d'etre--that your colleagues care whether you Linkedin-connect them--seems designed to trawl for idiots.
"In the worst case your LinkedIn account may be compromised. You will have to weigh this against the convenience of not having to log in to LinkedIn."
This doesn't convince me.
