freedesktop - Sep 2013 - [fdo] Is it good place to announce about new projects?

This question appeared after i noticed, that huge amount of projects, most of 
which was not known to me before, have own lists.

Before that i registered in xdg list thinking, that it is good to announce new 
projects (i even sent ther posts about two tools ? window-docker and 
fdopenres). They are too small imho, to dedicate lists for them, and as for 
first ? i don't know, what is better project to join it to (i created
fdopenres
instead of xdg-open for own purposes).

Now i'm begining much wider project ? desktop environment. First time some 
ideas or features would be implemented in existing projects as extensions 
(e.g., actions for file managers, allowing actions, specific for two-paned fm 
like mc, but between any two windows, e.g. current and previous focused).

I already created entry on the launchpad, though probably, i could move to 
other hosting, like savannah.  Both allow to have per-project mailing lists, 
but first time, probably, it must be announced in some public place. For linux 
audio there are lists just for such common discussions, not focused on single 
project, having own list ? LAU, LAD, LAA, and probably some other ? 
linuxmusicians. But there i found only freedesktop list. Is it good for such 
purpose?

My project doesn't have nothing implemented yet, there are only proposals
for
some features (imho, killer features). On launchpad it is just a several 
blueprints, containing descriptions (not sure, is it good usage of blueprints, 
but i looked for example some blueprints from inkscape and unity projects).
