Since launch of a new site (Feb 2015), if your question is about Vi/Vim editor or its plugins, you should consider posting questions at the dedicated [Vim Stack Exchange][1] site where it belongs.

However if your question is not about a compatible text-editor with the original Vi (such as [vintage-mode][2] in Sublime, evil, etc.), it should still belong to [SuperUser][3], unless it's about Unix shell (such as [vi-mode in shell][4]), then post it at the [Unix SE][5]. See: [What is considered to be vi?][6]

Questions about programming (such as regex), they still belong to [StackOverflow][7].

If you think you posted on the wrong site, flag the question to be considered for [migration][8] (not older than 60 days).
