One of the major downsides of chat rooms is that ignorant people may pose as experts. If someone states they are a keratotomy expert then how can this be verified? If you have expertise in the field of keratotomy then you'll be able to verify their credentials. It's a matter of picking the expert from the fake.
Talking of fakes it's sad to see so many keratotomy fakes bombarding email servers with unsolicited spam emails trying to sell keratotomy. Spam is a great threat to how the Internet works. Our website does not contain any email addresses for this reason. If you visit the keratotomy linked site above you will find that they treat your email address with great respect.
Talking online real people who are very knowledgeable about keratotomy can be like attending a real keratotomy convention ... except that there are no airfares or accommodation expenses.
