Not so much with the present-day anarchists. They make a showing at the G8 summits, but not much more than that (and that's still a Hell of a lot more than can be said for the Serious lefties). But if you read their manifests, they specifically eschew political platforms as reactionary. Libertarians on the left.
Now, that's not to say that they couldn't be effective. The right has used right-wing libertarians to move the Overton Window quite effectively. But I don't see anything in their public statements (or their operational planning) that suggests that they are working along those lines.
