I use Facebook (software written by not a qualified software engineer Mark Zuckerberg) - have no problems during last 10 years.
But thank you.
Aha - and what has @CfB written that is equivalent to Facebook?
(don't tell me that IOTA is as even the first version of Facebook was much better written than that crap)
Where can I view the source code of first version of facebook ? Or you are talking about GUI ?
