people get laid in real life.”

- Paraphrased from Paul Graham



new applicationfriends for sale



friends for saleit’s

... hot or not with a market economy

... a dating app without ‘dating’

... kinda kinky

direct user to user interaction

every touch point is a viral channel



engaging

virtual economy with a twist

low pressure social interactions... and flirting

makes for a great, cynical dating app



universal

everybody is vain

everybody has a price

everybody wants to flirt with hotpeople

scalability



“... unless you’re onFacebook.”



scaling is a requirement0 - 1 million pages / day in 4 weeks

... is pretty slow on Facebook

Don’t be this guy:

“We need servers. Anything you can spare, and we needthem NOW. We’ve doubled our servers and doubledagain and Facebook just eats them up.” - Ali Partovi (iLike’s CEO)



scaling

memcached, memcached, MEMCACHED

good hardware, well configured

good host (Softlayer ROCKS)

you NEED an awesome MySQL DBA



development

ruby on rails

(in the top 5 largest installations on the internet, by page views)

rfacebook

(good for getting started, but had to write our own for

maintainability and performance)



does rails scale?dumb question, but I guess.



architectures scale,

frameworks don’tanything scales on the right architecture.

focus on the architecture and operations.



the future

the platform is six months old.

movement towards engaging, deep apps.

the landscape is wide open.

what did the web look like six months into it?



the end.
