There is no harm in having a bit of optimism in what might be. I don't think it's right to write-off someone or something this early. The guy hasn't been sworn in yet. I admit that it will be naive of us to think that things will change all of a sudden or that it won't be business as usual but people don't seem to expect anything good to come out of Africa and are quick to play down any form of hope.
If I recall correctly some western countries felt elections will not hold in Nigeria, yet it did. They also said Nigeria will split in 2015 but no sign of that happening yet. There is always a new beginning so let's hope this is one for Nigeria
