You'd think asking people to "manage drafts" was some laborious and irksome chore… I'd argue the opposite. For me, having only one draft SERIOUSLY wigs me out.
The brain is a complex machine. People - and the world around us - are by nature, ever changing and complicated… Unfortunately, as is proven by the faceless down-voting of this thread.. "some people" often forget that everyone except themself... is "having a different life experience".
On drafts: we know the capability exists.. (we are able to have ONE draft). However, the current implementation's essential lock-in to a single-train-of-thought - is heavy-handed and unnecessary.
The more flexible a tool becomes, the more adept and comfortable people become at using it. A fear of feature-creep is the enemy of innovation - and only warranted in an environment lacking in sound judgement and effective checks and balances.
Don't assume what people want. Meta is overrun with control-freaks, IMO.. whom for one reason or another are very averse to change. I swear, everyone needs to take a deep breath sometimes, step back, and realize what we're trying to do here.. Provide an accessible and adaptable system for PEOPLE. Provide as many ways to interact as possible, and strive towards breaking down barriers to entry.
As the site matures, it is becoming more and more about new ways to allow new, (or possibly former/disenchanted) users to explore and contribute in their own, unique ways.. even if it's not YOUR way… This kind of flexibility will lead to more rich contributions, and a better community.
