Entrecard has been good to me, creating access to great blogs that I might otherwise have missed in the teeming multitude of the online community. Dropping on these sites enables me to see the latest (if any) posts by writers whose work I admire and enjoy. Though it might appear a bit hinky to acknowledge others' work by dropping on it, this form of currency is not meant to compete with pigeons but to establish an exchange rate of real value, which is to say established by the quality of the work. I've really come to appreciate this unique aspect of Entrecard.
Forums are something I miss, a bygone aspect of Entrecard that seems now like part of a distant and simpler past. They provided direct contact with the network on a variety of topics, the kinds of things you don't often discuss in personal messages with people you've never a met but enjoy conversing with on intelligent and stimulating subjects. Now I fall back on comments, which are even more impersonal. I would like to see the forums return. It would also be good to see better diligence on buggy sites. Not that it happens often, but every once in awhile there is a run of bad blogs that make me question Entrecards' due diligence. I've come to realize the value of connections with "good" blogs sufficiently to keep me dropping; by the same token, the slightest increase of viral sites in this community could easily drive me away.
Overall, Entrecard has been a positive experience and I expect to continue dropping for the foreseeable future.
