It all depends on whether the paper fits the journal. Minor journals serve a useful service as a repository for minor results. And minor results are still worth publishing because they might provide a detail or technique later needed for a major result. The thing to be wary of is when you see a stunning result that should really be in _Nature_ or _Science_ in some minor journal. Why isn't it? Was it submitted there first and rejected? It would be nice if the history of a manuscript (and its peer review) stayed with a manuscript so you could see if the authors really corrected problems brought up by peer review or were just spamming journals with a flawed manuscript until they found one that published it.
