No worries on the delay: totally understand paternity leave.
Are the selections editable? I am not seeing a clear way in the interface for me to tweak suggestions.
I am just thinking that there is no value added beyond the fully hand curated "see also" and Navboxes: esp. when the links you are adding are either a) already linked in the article (this is already the case with something like 1/4-1/2 of the results I am seeing -- sometimes its even the article itself (I think this problem might be associated with redirects)) or b) so central to the network, that they ought to be common knowledge -- or can be found really easy through link chaining (vis-a-vis the behavior promoted in http://thewikigame.com/ ). The problem, I think, is that you are using a tool designed for getting a "closest to the search term" result (Cirrus search) to do something that ought to be focused on the "nearest, as in same neighbourhood of knowledge".
The real value of linking in Wikipedia for our readers, is the hand curated incongruities between what our readers thought they came to Wikipedia for, and the long chain of other things that are connected to that topic, which excite their curiosity. If you plan to enable this tool: it really ought to provide "unexpected but rationally connected" results that excite the imagination, rather than a) known quantities or b) stuff that doesn't need more attention by potential new editors -- even if its new or different. This tool seems to be at the opposite extreme of the Random Article tool: it provides almost too obvious/central topics that aren't exciting. It would be great to have a list of articles, editable by (admins?), which could be excluded from the results, to force the algorithm to work around these unusually central/important articles as assessed by the algorithm.
I like the idea of pushing more exploration of our Wikis (this is a really valuable engineering effort), and for smaller Wikis which don't have the level of micromanagement of connections (links, categories, navboxes) that happens on English or some of the higher volume edit Wikis, this tool as it stands might makes sense. However, on the bigger wikis, Editors much less flexable than me will be very angry about the tool circumventing their long, hard, hand-curated work AND producing unusually not useful links, when this tool could be doing something that creates innovative new "ah ha!" moments (that serrendipity moment, that makes library research so fun: I would highly recommend reading: http://dp.la/info/2014/02/07/planning-for-serendipity/ ).
The algorithm is just not sophisticated enough and really needs a way to be managed locally so that you aren't having to anticipate the community's tweaking needs centrally. If you could define: a) the variables that rate pages, b) provide an interface where admins could tweak those variables to meet something closer to consensus needs, and exclude pages, c) do more testing with people that see hundreds of pages a day (editors), d) machine learning that prioritizes the kinds of connections that people click through on, I think you would get something that would be really fun for the communities to play with and use. But as it stands now, its not useful in the grand scheme of things: it neither promotes exposure of interesting content to readers, nor exposes them to "new/different/esoteric" content that many of our editors pride themselves working on.
P.s. Some more examples of not useful linking ("useful" ones are the exceptions). Based on this set, you are talking 3 out of 18 links that encourage someone to explore the depths of Wikipedia around similar items, rather than the surface or topics that are already common knowledge:
https://en.wikipedia.org/wiki/Yazoo_and_Mississippi_Valley_Railroad Listed articles: Memphis, Tenessee (central in link network), W.C. Hardy (bizarre, possibly central to network?) and Alabama (central in link network)
https://en.wikipedia.org/wiki/Aim%C3%A9_Ngoy_Mukena Military of the Democratic Republic of Congo (linked on page), Democratic Republic of Congo (linked on page), Lubumbashi (bizarre, possibly central to network?)
https://en.wikipedia.org/wiki/Francis_Patrick_Donovan Gough Whitlam (useful), Stanley Bruce (useful), Australia (central to network, linked on page)
https://en.wikipedia.org/wiki/Thomas_Meehan_(writer) Musical theatre (central, and linked on page), Maury Yeston (Unexpected, interesting connection: useful), Hairspray (2007 film) (linked on page)
https://en.wikipedia.org/wiki/Michael_E._Smith Aztec (central), OCLC (central and bizarre), Nahuatl (central)
https://en.wikipedia.org/wiki/James_Morrill Minnesota (central), W.E.B. Du Bois (central), Michigan State University (central and/or tangential).
