i have been trying to find a nice work-around to make collapsable posts in blogger

you know - like - it gives the first 100 words or whatever you decide and then it has a little "read more" link after that. seems it's rather complex as it stands now and i have tried a couple of suggested methods but none of them has worked so far :( can blogger itself please incorporate this as a basic blogger feature? shouldnt be too hard, in the posts settings it could say something like "limit homepage post to 100 words" or whatever - then it would automatically add a read more link. i love blogger but it is a major missing feature. i noticed the need for it after i added all that extra text to the DDR National Anthem article and wished i could collapse it. Well, maybe in the next update to blogger?
