I hesitate to use my serger because I don't feel that I have as much control in making 1/4" seams with the serger like I do with the sewing machine. But if you are comfortable with it - go for it. I know they have demonstrated how to serge pieces together for a quilt at my sewing club but I missed that time.

I think the seams would be rather bulky, and the seams wouldn't be 1/4 inch. On some quilts that may not matter. But some quilts for the design to be right the 1/4 seam is important. Good quality fabric does not ravel.
If you are having trouble with fabric raveling, buy better quality fabric to elliminate this problem.

I have serged some blocks together and the work was nice and even. The drawback was that it did add bulk to the seams. However, I do serge large pieces together for quillt backings. The seams are nice and even.

I wanted to try it so I pieced a shower curtain. That way the bulk of the seams was not an issue for quilting. It went together pretty well and I was pleased with it, but I'm not sure I would do it for a quilt.

I haven't tried that yet but here is a book i have seen on Nancy's Notions' website about that

I have not done this but I have certainly fantasized about it! You could really go to town on it doing a scrap quilt.

A friend of mine only uses her serger and no other. It has a perfect 1/4" seam and she swears by it. I'm addicted to my 201 but I do have a serger. I've never used it for quilting though.

I have not used my serger for piecing a quilt, but I have used it for the edge before putting on the binding. I did it on a baby quilt and it finished really nice. I do not think that I would do this to a full size quilt. I have been told that you cannot quilt a serged quilt, but I have done it in the past. Yes the seam is a little thick, but it was not an issue for my machine.

I have a serger, in fact 2 sergers, and use them for apparel assembly and edging fleece throws. There are a few issues to consider when using a serger for quilting. The seams become bulkier from all the extra thread, and if you are using white or light color fabric, that will show through to the front. I have a long arm and it is not too crazy about bulky seams. It works wonderfully for making flannel quilts where you will be doing a simple SID or straight line quilting. Another thing I find, is that the seam draws up a little if you use too close a stitch, causing some puckering of the fabric...ironing takes this out of most serger sewing, but after laundry it is back to the slightly puckered state. So you need to think about these issues before you decide to use the serger. Make some block samples first and see how you like it. As stated before, I wouldn't use in on a complicated block design. Nancy's Notions has some great ideas for using the serger in your quilting.

I used my serger when I made a blue jean quilt for my grandson and it worked well and sure kept the ravels under control. It probably is a little thicker at the intersecting seams. For quilting I only did horizontal rows of regular stitching across the middle of each block/row. I did have a bit of problem with not all the blocks being the same size, which came from not being accurate with the seam allowance. I would use it again with certain fabrics.
