I used to. They're a decent compromise between the advantages of clipless and the advantages of standard platforms, giving your foot a fair bit of stability and a good position, but still easy to dismount and no inconvenience of crunchy feet.

They have some downsides, though.
- Mounting with them takes a bit of getting used to. Muscle memory takes care of it now, but flipping the pedal correctly isn't instinctive at first.
- Some shoes don't work very well. If the toes of your shoe are fairly high (lots of wiggle room up and down), you can't get the shoe all the way in. They definitely won't work if you routinely ride in work boots, winter boots, etc (fashion boots might work, but the toe clips may ruin the fashionability).
- Related to above, they do wear down the tops of your shoe if you use them a lot.

In the end, I gave up on toe clips, and use a platform/clipless reversible pedal instead. I commute in normal shoes, but have clipless available for longer rides where I can get more benefit from them.
