   Format: MarkdownItexWhat's the precise idea of where the two senses of spectrum meet, that the spectrum of the sphere spectrum has Morava-K theories as points ([arXiv:1401.1044](http://arxiv.org/abs/1401.1044), p. 10)?

   Format: MarkdownItexI have added the statement that in $Spectra$ homotopy cartesian squares are equivalently homotopy cocartesian, with some remarks and pointers. Also re-organized slightly and added cross-link with _[[stable homotopy category]]_. <a href="https://ncatlab.org/nlab/revision/diff/Spectrum/7">diff</a>, <a href="https://ncatlab.org/nlab/revision/Spectrum/7">v7</a>, <a href="https://ncatlab.org/nlab/show/Spectrum">current</a>

   Format: MarkdownItexAh, now I see why this page was so empty: There is also _[[stable (infinity,1)-category of spectra]]_ and the two should probably be merged.

   Format: MarkdownItexHm, it may be tedious to merge these entries in a satisfactory way. Maybe instead I'll give the section on finite homotopy (co)limits of spectra its own stand-alone entry, for ease of `!include`-ing it into relevant entries (such as these two, but also _[[stable homotopy category]]_ etc.).
