We have been using the plugin on single installations and are very happy with it.
We just installed it though on a multisite (wordpress v3.5.2 + Shareaholic v6.1.50). We do NOT have it network-activated. We only activated it on a couple of the sites and noticed a “weird” behavior.
The plugin “picks-up” and recommends posts from site A on pages and posts on site B!!!
Is this a bug or is it the expected behavior?
In any case I believe there should be an option for this. I mean: every individual administrator should have a choice/option to recommend posts other than the ones of his/her site.
Can you imagine the scenario on a multisite e-shop installation where I get to -under MY products’ posts- recommend NOT my own products but someone else’s… ?… 🙁
Recommendations picks up posts/pages from the same (sub) domain. So for instance, if you installed Recommendations on sub.domain1.com, it should only pull URLs from sub.domain1.com and not sub.domain2.com or sub2.domain1.com
