Absolutely agree, it's a great initiative and at this stage, when it's in its trial stages, it's hard and perhaps a bit unfair to be critical.
I just feel like their attempts at being a bit off-beat etc come across as contrived. They don't need a master plan as such, but do need to think about it more without looking like they've over-thought it, if that makes sense. Still, it's a good thing and will hopefully find its groove, when it becomes more permanent.
As ever, Melbourne's a great example. The development of its lane-ways has happened over time, so the graffiti and crates for seats etc have grown into the streetscape and don't look like they've just been dumped somewhere. It'll happen here too and it'll be a great thing when it does.
