Biscuits are a good alternative when edge joining boards particul,arly because
they help align the boards so that the edge seam fits very closely. The
biscuits also provide added strength to the joint because they increase the
area of gluer surface but usually that added strength isn't needed. The area
along the edges of the boards usually provides sufficient glue area.
There's a new tool that's being introduced in a month or so from Festool called
the Domino which will cut biscuits shaped like smaller mortises. The mortises
are cut because the cutterhead oscillates to produce the deeper straight cut of
the mortise. The Domino comes with precut strips of wood that serve as floating
tenons and which are sized to fit those mortises exactly. The tool appears to
be a fabulous improvement and is one of the few really new and imaginative
concepts, but, unfortunately, it's very expensive. The tool with one cutterhead
is projected to cost $700 and an additional $200 to buy different sized
cutterheads.
