If the tradition is to have many parties in the parliament and government, it's not going to be hung because MPs are used to talk and compromise. I say this with the Swiss perspective: even the government is always formed by the 4 most important parties and has to work together - if any minister handles against its own team it gets kicked out and replaced by another from the same party. This also reflects positively on the electorate itself which will have expectations of compromise and talks. And also allows for new parties to rise and have a real voice. Edit: downsides: stuff gets moving slower (until they reach compromise...) and the electorate is less motivated (let them find a way among themselves...)
