As long as the discounts are good, I'm not going to miss daily and flash deals, this just streamlines the event without me having to check back every 8 or whatever hours. I can appreciate just buying what I want at my pace without worry of a flash price popping up later and kicking myself in regret.
You know what can go to hell? Seeing a game you want as a vote option for a future flash sale and no one votes for it. I remember this happening to Ikaruga the first Steam Sale it appeared on, and it was the only time during that sale that it was an option to vote for, so of course it didn't get a flash deal.
