I hate Twitter less than Facebook, but I still hate it. I use it to interact with people I know, to stalk people I admire, and to read news from sources I trust. I even, just occasionally, tweet.
I don't like that Twitter creates an archive of my tweets that exists for ever. What I think now may not be what I think next week, nevermind next month, next year, or next decade.
So, from now on, all my tweets will delete themselves roughly two-weeks after they're posted. The same goes for 'likes', though that might take a little longer.
If you don't like that please do write your feedback on a postcard, and then keep it to yourself :)
