Lua.microblog is a microblogging framework for the Lua programming language.
Several considerations. Python has more libraries, but for a microblogging client, Lua is much more lightweight and should thus provide better interactivity. For someone used to functional languages, Lua is also a more attractive option — it has full tail-call optimization. Finally, I am inspired by Greg KH’s Twitter/Identi.ca client, bti, which is written in C. One does not need an abundance of libraries to get things done!
