                                 Page 17 of 20




            On December 28, 2000, Abra LLC entered into a Voting Agreement
with the Company (the "Abra Voting Agreement") pursuant to which, among other
things, Abra LLC (i) agreed to vote (or cause to be voted) all of the shares
of Company Common Stock beneficially owned by Abra LLC on the record date of
such vote or action (a) in favor of the Merger, the execution and delivery of
the Merger Agreement and the approval of the terms thereof and each of the
other transactions contemplated by the Merger Agreement; and (b) against any
amendment of the Company's certificate of incorporation or bylaws
which amendment would prevent or materially impede, interfere with or delay
the Merger, the Merger Agreement or any of the other transactions
contemplated by the Merger Agreement and (ii) appointed the Chairman and
Chief Executive Officer of the Company and the President, Corporate
Development of About, or any other designee of the Company, each of them
individually, as Abra LLC's proxy and attorney-in-fact (with full power of
substitution) to vote or act by written consent with respect to Abra LLC's
shares of Company Common Stock.  The Abra Voting Agreement terminates on the
earlier of (i) the effective time of the Merger and (ii) the termination of
the Merger Agreement pursuant to its terms.

            On December 28, 2000, Abra LLC beneficially owned 2,236,641
shares of Company Common Stock, which amounted to 10.46% of the total
outstanding shares of Company Common Stock.

            On December 29, 2000, the Company entered into a definitive
agreement (the "List Rental Agreement") with PRIMEDIA Magazines, pursuant to
which the Company will issue 120,987 shares of Company Common Stock to
PRIMEDIA Magazines in consideration of the provision by PRIMEDIA Magazines of
the right to use a mailing list owned by PRIMEDIA Magazines. The shares of
Company Common Stock to be issued to PRIMEDIA Magazines pursuant to the List
Rental Agreement were valued at $2,450,000 based on a $20.25 pro forma
equivalent per share value of Company Common Stock. Pursuant to the List
Rental Agreement, 120,987 shares of Company Common Stock will be issued to
PRIMEDIA Magazines promptly.

            The foregoing summaries of the Abra Voting Agreement and the
List Rental Agreement do not purport to be complete and are subject to, and
qualified in their entirety by reference to, the provisons of the agreements
filed as exhibits hereto. A copy of (a) the Abra Voting Agreement is attached
hereto as Exhibit 10, and (b) the List Rental Agreement is attached hereto as
Exhibit 11.

            From January 2, 2001 to January 3, 2001, Abra LLC and PRIMEDIA
purchased an aggregate of 199,000 shares of Company Common Stock for an
aggregate purchase price of $5,291,556.90 in cash. Of those shares, Abra LLC

            The Reporting Persons may, from time to time, acquire additional
Company Common Stock in the open market or through privately negotiated
transactions.

            Except as set forth above, the Reporting Persons have no present
plans or proposals which relate to or would result in any actions described in
subparagraphs (a) through (j) of Item 4 of Schedule 13D.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

            (a) The responses of the Reporting Persons to Rows (7) through (13)
of the cover page of this statement on Schedule 13D are incorporated herein by
reference.

            Except as disclosed in this Item 5(a), none of the Reporting
Persons, nor, to the best knowledge of the Reporting Persons, any of the other
persons named in Item 2 or on Schedule A hereto, beneficially owns any shares of
Company Common Stock.

            (b) The responses of the Reporting Persons to (i) Rows (7) through
(13) of the cover page of this statement on Schedule 13D and (ii) Item 5(a)
hereof are incorporated herein by reference.

            As further described in Item 4, PRIMEDIA and Abra LLC purchased
an aggregate of 199,000 shares of Company Common Stock in the open market for
an aggregate purchase price of $5,291,556.90. These acquisitions of Company
Common Stock as described in Item 4 may mean that Abra LLC, PRIMEDIA and the
other Reporting Persons are a "group" for purposes of Rule 13d-1 of the
Securities Exchange Act of 1934, as amended. In addition, because of
PRIMEDIA Magazine's right to acquire 120,987 shares of Company Common Stock
pursuant to the List Rental Agreement, PRIMEDIA may be deemed to be the
"beneficial owner" of those shares.

            Except as disclosed in this Item 5(b), none of the Reporting
Persons, nor, to the best knowledge of the Reporting Persons, any of the other
persons named in Item 2 or on Schedule A hereto, presently has the power to vote
or to direct the vote or to dispose or direct the disposition of any of shares
of Company Common Stock or other securities of the Company which they may be
deemed to beneficially own.

            (c) Except as disclosed in Item 4 hereof, none of the Reporting
Persons, nor, to the best knowledge of the Reporting Persons, any of the other
persons named in Item 2 or on Schedule A hereto, has effected any transaction in
the Company Common Stock during the past 60 days.

            (d)  Not applicable.

            (e)  Not applicable.

            Neither the filing of this Schedule 13D or any amendment thereto,
nor anything contained herein is intended as, or should be construed as, an
admission that the Reporting Persons are the "beneficial owner" of any shares of
Company Common Stock or other securities of the Company.
