I don't think it's really necessary to mention it in the post's title.
When there's that little text icon, it means the post contains extra content.
Noted
Maybe the title mention was so you could read the archive? I'd think the best approach is link the archive in the title, then include a link to the original in comment (without mention of any of this in title).
The system does a poor job of pulling "title images" from the archive and as such less people pay attention. Thus the reason I started linking the original source and putting the archive in the comment rather than in the primary link. People like pictures. What can I say?
