iTalki is a long-standing player in the social language learning space. It is one of the largest language exchange communities in the world and there are loads of native Hebrew speakers waiting to share their language with you in exchange for help learning your native language - for free.
iTalki has developed an intuitive interface for finding Hebrew exchange partners (along with dozens and dozens more languages) which makes it quick and easy to locate, contact and quickly begin sharing with them.
Once you connect with a Hebrew speaker on iTalki, you can then initiate a live conversation with them via voice and video calls directly over the Internet. Depending on both of your connection speeds, you can use either audio or video!
iTalki has such an expansive user base that the chances of you finding a Hebrew language exchange partner is incredibly high, no matter what your native language is. English - being such an international language and a worldwide business lingua franca - is of course in high demand.
All that said, you do need to take into account the fact that not all Hebrew language partners are equal and many people - though native Hebrew speakers themselves - might not be truly effective at helping you learn.
Enter the iTalki Hebrew tutoring program, a non-free but also not necessarily expensive option for those seeking to get qualified, professional help learning Hebrew online.
The iTalki interface allows you to see feedback about Hebrew tutors as well as compare the prices at which they offer their services.
You can even get a free trial with many tutors first in order to see if they will be a good match for you.
By sharing a special link with your friends on Facebook, Twitter and other social mediums as well as your website/blog (if you have one), you can earn iTalki credit (ITC) which can be redeemed for free Hebrew tutoring sessions.
When you join iTalki for free, you will immediately be able to create a unique link to share. (After joining, go here to learn how to make links.) When friends click this link, iTalki knows you sent them and will apply credit to your account.
iTalki offers a variety of language learning articles, many of which are applicable to Hebrew.
