It depends on what your are promoting and how.

In Example: If you have a online shop with paintings that has an affiliate program I would say defenitely yes, if you promote the opportunity of commision revenue on painting sales.

If you are only trying to sell the paintings I would say no. You might get an occasional sale but revenue would be much better if you would offer those on a social site that does not consists for the major part of internet marketers but of  a general public. People who want to decorate a room, buy a special present, want a painting of their pet, etcetera.

This does not only apply for crafts but also for musicians looking to sell their music or any other productor services that is not related to home business, earning money and getting traffic. With the exception for crafts as graphic and web design.

An other example: say you sell products for cooking and baking. How big you think the chance here on APSense is to sell a set of pans of fkitchen gear to bake pies? Sure the are people here on APSense and other business networks that love to cook and bake. However when they visit APSense they are not focused on these interests but on promoting their business.

So what could be an approach for the cook and bake example? Well, I would start or join a group or a community about coocking and baking that has members from the general public of all layers. And I would start writing articles about recipes, tips for cooking and baking, product reviews of new kitchen gadgets, etcetara. Without pushing my store. You see when people read and like your content they will see you as an authority and come to you when they need new kitchen equipment. You could also join another group i.e. about health and post some healty recipes in that group, thus reaching an entire new crowd!

A place where you can do that is the new Kooiii where the focus lies one sharing interests and having fun. Advertising is limited to restricted areas (you can of course put your business on your profile). You can advertise in exchange for activity points you can buy or earn by being active. 

This post shows a direct example of how to properly use Kooiii's simple tools to market your blogs and article based websites effectively. By the time you are done reading you will realize how powerful they are for your online business marketing.
