Its really mainly a rationalization for paying some people more than others. Or just a way of rating some developers as being more valuable.

If it were popular to use Programmer I, Programmer II, and Programmer III, then they would call it that.

By the way, going to a lot of conferences or having a lot of Twitter followers does not make you more 'senior' than me. It might make it easier for you to negotiate a 'senior' title and salary though, just by virtue of your being good at self-promotion.

They do, in lots of companies, have "Software Developer I", "II", "III" ...

Or MTS/SMTS/LMTS/PMTS with a gazillion different levels for each
