I would agree that solutions to overcome the initial problems can be found. The upcoming Hardfork is, supposedly, going to address at least part of it by making account generation quicker. There are other aspects to consider as well, though.
Steemit is poised on the cusp of growth that will benefit everyone here providing it is managed correctly. I, for one, hope to see it overcome limitations and find it's true potential.
Thanks for posting @gadrian!
