I'm afraid that due to the changes twitter has put in place we will have to "retire" our twitter features just as they have retired their older api that they depend on because there is no longer a way that we can easily make it more user friendly than generating the widget and pasting it in. This is the same reason we never made a feature for Facebook profile widgets, because it requires generating the widget at facebook which includes a specific id that FB generates. If you have to generate the widget and copy part of it you might as well just copy all of it.
Twitter used to be an open platform but they no longer want any access to their api without tying it to a specific account so that they can limit the amount of access and prevent anyone from over-using it or managing to monetize use of it beyond their control. You can find a lot about this by googling "twitter is no longer an open api" but much of it is summed up in Don't Use That Open API It Could Be a Trap.
The bottom line is that it isn't that hard to generate their widget and paste it in but their dropping of the older api has burned us and makes me regret having ever implemented a "feature" for it in the first place. But people will have to forgive us for retiring our feature if they forgive Twitter from dropping their older more open api and if they don't forgive twitter they should still forgive us since it is beyond our control.
Best,
Joe
