Accessibility concerns: form inputs
UserVoice uses the following markup pattern for its user idea inputs:
<span class="uvFieldPlaceholder">Label text</span>
…which looks good at first glance until it becomes apparent that as soon as one starts typing in a field,
uvFieldPlaceholder is hidden with display:none and is therefore inaccessible.
Additionally, when editing a previously posted idea, the form <label>s containing the inputs have no text at all.

Noting above that the inability to post code like one can on Github or StackExchange or umpteen other platforms is poor.
