Oh you mean my account? lol yeah I'm new to Twitter (only few weeks now), and just using it to like / retweet others' postings about our product. However, does it against Twitter's policy?
I've been using some good frameworks in PHP such as CodeIgniter, Fuel, Zend, etc, but nothing can compare to Ruby on Rails.
A major advantage of ruby world is most open-source libraries and gems are actually usable and well written and maintained, whereas most PHP open sources are not maintained well or have a poor code quality.
I guess PHP is easiest to start, Ruby and Python are more fun. Javascript is obvious if you consider web programming.
I'm interested in Scala, GoLang nowadays, but I feel it's in too early stage still.
Anyway I would recommend just trying every language, so you can select the most suitable one depending on the project.
