At the moment I am preparing new version of the OoxAcceleratorRss program.
I build previous version with C# and was quite successful and wanted to improve it. I ran into some problems which are html-related and I got stuck. I had to design and build a better html parser. One that is able to correct all kinds of html errors.
I read that one of the features of F# is the lexer and the parser. So I intend to learn F#.
