Should law firm sites include attorney contact information and e-mail addresses, just the firm’s general contact information, or fillable generic forms to send to the firm?

It can include all of the above, or it can include none of the above. It really depends on the law firm. Some firms promote a cultural of allowing clients to contact partners and associates (whether its electronically or via the phone). Other firms shield information and only have a direct point of contact with a senior partner. If your firm is open and wants calls or emails to anyone, then post everyone’s info. If your firm wants a single point of contact, then put the partner’s info or generic contact info for the firm.
