Delphi increases in popularity

I've been developing software using Delphi for well over 15 years and for at least the last 10 years I hear all about how Delphi is dead and developers are moving to other languages. I have just looked at the TOIBE index which list software development languages by popularity and Delphi has moved from ranking 15 last year to 13 this year, so this shows that Delphi is going to stay around for some time to come.

Obviously these ranking change constantly and it could be next year Delphi goes back down the list, but I do think it says shows that Delphi is not dead and that all the people who have said 'Delphi is dead' for the last 10+ years are wrong.

Prefix class with 'I'

The other week I was looking at some code another Delphi developer had written and noticed that he prefixed classes with 'I' instead of 'T'. In my world the prefix 'I' means its an interface, but he argued that an abstract class is an interface and that all abstract classes should be prefixed with 'I'. I disagreed with him for various reasons, one being that Delphi standard classes do not do this.

Does anyone else prefix their abstract classes with 'I' and only use 'T' for concrete classes?
