Ouch thread going havoc
NO - I'm NOT talking about camelcase autolinking (which I really dislike)
I'm talking about this:

Ok, so to sum up it seems people don't have any particular arguments
against titles as links.
Danielo mentions possible
confusion for users, presumably that clicking it doesn't lead anywhere, but I frankly thing few would be confused by this. (Particularly if the title was not styled as a link). AND, clicking the title link
does do something; It scrolls the window so the tiddler is at screen top if it wasn't there before!
As noted, the other advantage is when copying tiddlers between TWs. This is perhaps not needed all that often BUT in public TWs, I find a tiddler every now and then that I want to copy and where the link simplifies.
Anyway, thanks everyone for the input.
