Can you give an example of such functions? Almost every core WordPress function either has a get_*() analog, or else incorporates apply_filters().<div><br></div><div>A dynamic sidebar *inside* of the_content()? That sounds somewhat fraught with potential problems...</div>

There are some specific uses I can think of:<br><ol><li>Some functions have no "echo" parameter and always print the output. If you wanted to run a filter over the output of such a function, this seems like an easy way to do so.</li>
<li>Ad hoc insertions of widgets/widget areas. Let's say you have defined a sidebar that you want to be able to insert within your posts. You could do this by defining a shortcode, which prints out dynamic_sidebar in an output buffer.<br>

There are many reasons to use output buffering (ob_start etc), but<br>
they would rarely be used within a theme. I've seen themes which use<br>
buffering as a way to dynamically minify the markup, but that's a<br>
horrid way to do it - much better incorporated within a caching plugin<br>
IMO.<br>
<br>
There may be a practical use for output buffer in a theme, but I'm<br>
darned if I can think of a good example. I wouldn't want to see it<br>
banned outright, as someone may come up with a cunning use for it that<br>
none of us have thought of.<br>
<br>
Perhaps the theme check plugin could check for output buffering<br>
functions and leave a request for the theme developer to provide a<br>
reason for using it? That way they'll know it's non-standard and<br>
provide a reason (good or bad) for the theme reviewers to read. Could<br>
potentially save a little to and fro'ing in the future. Just an idea.<br>
