Is there an easier way to remove single vertices in mesh than delete and reconnect? When stiching two meshes together sometimes the number of vertices don't match.

I could delete the red vertices and reconnect the remaining with Make Edge F. 

Is there a more efficient way to do this, like adding a vertex using Subdivide W?
You can dissolve a vertex with X > Dissolve Vertices or you could also get rid of it by merging it to the next closest one by selecting it, selecting the other choosing a merge option (AltM).
