Yep, there is an issue with automatic qualification. We don't get to polish the song before the final (for example, Serbia seemed to improve between the two heats) and there isnt the same familiarity.
Didn't harm Italy did it? If we enter a good song the semi-final isn't an issue, though personally I do think now only the winner (or perhaps the top 3-5) should qualify and the "big 5" go through the same process as everyone else. Nobody in the UK watches the Eurovision Song Contest for the UK entry anymore (as generally we're ****), so it wouldn't affect BBC viewing figures at all.
Also Graham Norton did a superb job last night - light hearted but unlike Wogan he understands the contest and that people don't vote for us because we enter **** songs, not because of the myth of political voting. I think he gets the tone just right, although like with BBC3 do wish that during the intro and one of the recaps he'd keep quiet.
P.S. The televoting results have been announced and Italy would have won if it had been on public vote alone, with Sweden third behind Russia. The UK would have got a couple more points out of it and finished 24th and just to rub it in, Austria would still have had 0.

The UK televote put Lithuania at number 1, followed by Poland, Sweden, Italy and Australia. Latvia, Russia, Belgium, Serbia and Israel complete our top 10, while France is last. The jury voted for Sweden then Australia, Israel, Italy and Latvia with Armenia in last place.

As for the future although I'd like to see what ITV or C4 would do with the selection process I do think at the very least the BBC need to return final responsibility for selecting the song to the audience - whether that's through a TV show or just through radio or online, at least let viewers pick the best of the worst, even if the audition process is pretty much the same. I also think it would give the act going through to represent the UK a bit of confidence if they knew they'd been chosen to do so by the fans rather than some unknown faces at the BBC.
