There are a zillion search engines out there, but a few stand-out for their unique qualities. I mentioned one in a previous post — Ask Vox, which allows you to ask a question and then actually hear an avatar speak the answer as well as seeing its text.
I recently discovered another search engine with special qualities — Sidekiq. When you do a search, it doesn’t just show a list of sites. It immediately shows good-sized pictures of the actual webpages where your search item appears.
The link to Sidekiq is under Search Engines on my English Themes for Beginners and Early Intermediate page. There are several other interesting search engines listed in the same category, all having some unique qualities that I think would be helpful to students in general and English Language Learners in particular.
