If you couldn’t already tell, we are big advocates of businesses using Twitter to promote themselves. Got an online fashion boutique? Tweet about your latest sales and offer followers coupons on their next purchase. Run a successful web design company? Tweet about your latest hosting sale and potentially gain some new customers. Own a trendy furniture store? Do not, I repeat, DO NOT use hash tags to spam trending topics in order to appear more relavant. This is definitely the wrong way to use Twitter.
