This is ridiculous. I have designed a number of personal and small-business sites so as to include beautifully custom Twitter feeds, and now all of these have been broken for far too long, now. What am I supposed to tell my clients? That suddenly Twitter won’t let them use a feed unless they buckle down and subject themselves to a terribly contrasting theme against the custom, individually designed websites I have produced for them? That they can just no longer use a custom Twitter app on their website at all anymore? Fix this, Twitter, for there is nothing beneficial about taking a step backwards to influence a greater control over your users. I’ve been a user since the site’s birth. That might just change if things aren’t improved for the better. Let designers easily customize their own Twitter feeds again.
