Theres nowt wrong with top posting or interspersed posting. Top is
partcilarly good for a quick comment reply.

Actually top posting, bottom posting, no trimming of quoted
text, broken or overlarge signature block, etc remain as useful
as they always have -- for quickly identifying the postings that
aren't worth bothering to read when you're strapped for time.

Those who write good concise informative responses tend to be
those who know how to communicate effectively and understand the
purpose of the quoted text, and thus provide their responses
interleaved in appropriately trimmed quoted text. The ability to
identify such responses with just a fraction of a second glance
is extremely valuable when you want to only read through the
best responses.

The insistence on bottom posting is a convention from days now gone.

There never was one. Top posters who didn't understand why they
shouldn't top post often incorrectly assumed they were being
asked to bottom post instead.
