On the "Is the expansion of space constant?" thread you use the logon names and a colon to flag who's talking, using this sort of exchange:

In that case, you follow a quote from tommac with your own response.

But here, on the same thread, you address publius directly, using his logon name and colon:

And here, on this thread (in the text I quoted before), you simply preface a stand-alone remark with your own logon name:

It's a little awkward to track who's addressing who. Using the quote facility allows your text to contrast with the text you're quoting, and allows us to link back to the context of the quoted text via the little arrow buttons.
