Maybe we should preface articles with the range of frequencies we intend to talk about - most aluminum electrolytics are inductors above a few hundred kHz (and some considerably lower).

There's also a controversy about whether their limited surge current capability affects their reliability in bypassing applications. Jeff Winslow
