I've just added a bunch of basic traditional characters, now I got about 300 characters almost "for free", although I haven't added any really new characters. When you already know 说, learning 說 isn't much of a difficulty, although this is different for characters like 機,聯 or 盡.
However, I'd still like to know the actual number of separate characters I know, so I'd be in favour of drawing a line between traditional and simplified characters in some way.
