Could we add a link to:
As Software Recommendations is still alive one year after question was posted I think that a link to it will be helpful to both sites.
This will be helpful to that site as it could get more traffic and increase it relevance and eventually graduate and will be helpful to Web Applications to eventually reduce off-topics questions.
Probably not a good idea.
The software recommendations site is still in beta, and while it looks like it's doing OK, there's no guarantee it'll survive. So while it's probably OK to point people there in comments, it's a little early to make a (semi-)permanent link from our site.
IMO an excellent idea. (And arguments about beta sites irrelevant since Software Recommendations has graduated).
