In this case, a more direct reference to the blog's middle name, i.e., Heteronormativity and Performativity. Ergo, HetPers. The final 's' was added to signify plurality. Many of my readers refer to the blog as 'HetPer' anyway, so for the sake of onomastic consistency I christened it 'hetpers.'
It will take up to three days, the Google machine informs me, for 'hetpers' to show on the search engines. So, for now, either write out the whole address on the navigation bar or simply wait a couple of days for the search engines to pick it up. Thank you.
