Don't you hate it when this happens? I've written too much lately, now I can't think of anything.
What do you do to cope with it? I used to make small giveaways, but a casual post should do just fine. Do you find it acceptable to write casual posts? I don't see anything wrong with it as long as the author doesn't push much vote buying into it.
There's even this post I've written about this, we need more light content! It's much easier to engage with and it heightens the sense of community interaction.
