This is the time of the year that thoughts turn to gardening as seed catalogs start filling the mailboxes. I enjoy having fresh-grown vegetables from my garden; nothing is better than a deep red, ripe, juicy Big Boy Beefsteak tomato right off the vine. These seed companies are overwhelmingly small to medium-sized businesses (SMBs). Many have gone online in the past few years, bucking the century-long tradition of depending primarily upon postal mail for their sales.
