DailyHaiku is open for submissions through March 31st. There's no pay for contributors, but it's good exposure, and if your haiku are chosen for the annual print anthology, you'll get a copy. Submit 10 unpublished haiku by email. No simultaneous submissions.
Several magazines just put out new issues that are particularly good. For online reading, check out the March issue of Niteblade. If you prefer print magazines, order a copy of the current bear creek haiku or Scifaikuest. All three magazines are well-stocked with good poems (and Niteblade's got fiction, too).
Finally, thank you to whoever (whomever?) nominated my poem "Bats" for the Rhysling Award. It's an honor to be a part of the talented group that always makes up the Rhysling anthology, and "Bats" was an especially fun poem to write.
