Classifieds are simply better when used online for both consumers and advertisers.

It is easier for consumers to find what they are looking for:

It is easier to search & browse online;
It is more effective to qualify interest when listings contain more descriptive information (e.g., more text, photos, virtual tours, etc.); and
It is quicker to make contact (just drop a seller an email).

For sellers, online listings are more convenient and cost effective:

Ads can be purchased more cheaply and in many cases are free;
It is easier to accept inbound requests via email (using an anonymous screen name);
Listings attract better prospects when they contain more descriptive information; and
Advertisers can edit or delete a listing at any time.

It also good for the environment, we can save a lot of flyer, paper, trees, and make our environment cleaner.
