I'm going to have to disagree with your points:
> First, as the top 10 chart in the article shows, the gaming money in Kickstarter is mainly in miniatures not in board or card games.
That non-mini board games don't dominate gaming money on kickstarter is irrelevant to whether kickstarter is pushing the current market in board games. About board game dominance on kickstarter, though: it seems to me that kickstarter funds more card and board games than any other class of things.
> Second, a large proportion of the games that get funded are traditional publishers using Kickstarter as an alternate preorder and marketing system, usually with absolutely tiny goals.
Those traditional publishers seem to be publishing 2-3x as many games as they were publishing pre-kickstarter, and/or have moved to an entirely kickstarted model, basically becoming kickstarter companies (Queen, Eagle/Gryphon, etc.) It's not the preorders that are so important, but the free, instant crowdfunded credit.
> A third decent sized chunk are reprints for old games, which while nice to have are hardly a sign of a renaissance.
When many of the classics of gaming were only available from 20-year-old German 2000 game print runs for so long, this can seem like the definition of renaissance. Virtually all of the bgg.com top 100 are in print. 5 years ago, a lot of those games (the ones that existed) would have cost a small fortune. With every passing day my collection becomes less valuable, but more people fall in love with the board games I like.
> What's left tends to not have much impact, or even be any good.
Agreed, but within class that are buried amazing designers like Martin Wallace and Phil Eklund, who have used kickstarter to become largely independent of the big publishers.
