I don't think the SMT's would be affected by the glitches at all for the glitches seem to be limited to the website steemit. This is confirmed by the fact that esteem, busy.org, chainbb, and steemfollower to name a few are not only working but seem to be running faster than ever. Since most SMT applications will run on their own servers and be coded by their own teams they'll function or bug out on their own merits. Given the bugginess of steemit as of late that probably is a good thing for the SMT's.
